EP-A-O ~47 488, FP-A-O 372 263, EP-A-O 426 948, EP-A-~ 434 940 and EP-A-O 492 171
propose cyanophenylpyrrole derivatives as acaricidal and insecticidal active ingredients in
pesticides. However, the biological properties of the compounds described in these
publications are not entirely satisfactory in the pest control sector, and this is why it has
been found necessary to provide other compounds having pest-controlling properties, in
particular for the control of insects and of representatives from the order of the Acarina,
and this object is achieved according to the invention by providing the present compounds
I which, surprisingly, are additionally also suitable for controlling phytopathogenic fungi.
Compounds I which have at least one basic centre can form for example acid addition
salts. These acid addition salts are formed, for example, with strong inorganic acids such
as mineral acids, for example perchloric acid, sulfuric acid, nitric acid, nitrous acid, a
phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, for example
unsubstituted or halogen-substituted Cl-C4alkanecarboxylic acids, for example acetic
acid, or unsaturated or saturated dicarboxylic acids, for example oxalic acid, malonic acid,
succinic acid, maleic acid, fumaric acid or phthalic acid, or hydroxycarboxylic acids, for
example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or benzoic acid,
or with organic sulfonic acids for example Cl-C4alkane- or arylsulfonic acids which are
unsubstituted or substituted for example by halogen, for example methane- or
p-toluenesulfonic acid. Furthermore, compounds I having at least one acidic group can
form salts with bases. Suitable salts with bases are, for example, metal salts such as aLkali
metal salts or alkaline earth metal salts, for example sodium salts, potassium salts or
magnesium salts, or salts with ammonia or an organic amine, such as morpholine,
piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, for example ethyl-, diethyl-,
triethyl-, or dimethylpropylamine, or a rnono-, di- or trihydroxy lower-aLIcylamine, for
example mono-, di- or triethanolamine. Furtherrnore, corresponding internal salts may
possibly be formed. Preferred within the scope of the invention are agrochemically
advantageous salts; however, the invention also comprises salts which are
disadvantageous for agrochemical purposes, for example salts which are toxic to bees or
fish and which are employed, for example, for the isolation or puri~lcation of free
compounds I or their agrochemically usable salts. Due to the close relation between the
compounds I in free form and in the forrn of their salts, the free compounds I, or salts
- 3 - ~ ,7
thereof, which are menlioned hereinbefore and hereinafter are also to be understood as
meaning analogously and expediently, where appropriate, the corresponding salts, or the
free compounds I, respectively.
Unless otherwise defined, the general terms used hereinbefore and hereinafter have the
meanings listed hereinafter.

circumstances, with cooling, at room temperature or with heating, for example in a
temperature range of approximately -~0C to the boiling point of the reaction medium,
preferably from approximately -20C to approximately +lSQC, and, if required, in a

The reaction is advantageously caTried out in a temperature range of from approximately
0C to approximately ~180C, preferably from approximately +10C to approximately

of the reaction mixture.
It is possible to prepare different products of the forrnula I when variant c) is carried out,
depending on the number of equivalents of halogenating agent used. At least two
equivalents of halogenating agent have to be used. By means of the first equivalent the
~', ?
- 12-
dihydropyrrole derivative VII is oxidised and the corresponding pyrrole intermediate is
thus obtained ("compoun(l A"). By means of the second equivalent of halogenating agent
the halogen substituent R2 is introduced into the 4-position of the pyrrole ring of the
compound A, thus yielding the corresponding compound I, wherein R4 is methyl
("compound B"). In order to obtain the corresponding compound I, wherein R4 is a group
R2CH2-, i. e. in order to mono-halogenate the methyl group R4 of the compound B, a third
equivalent of halogenating agent is needed. The term "equivalent" is to be understood in
this paragraph in such a way, that it comprises not only the exact amount corresponding to
the exact equivalent, but also a certain range, for exarnple approximately 10%, above and
below this exact amount. It is possible to isolate the cornpound A and/or the compound B,
but preferably the reaction is carIied out in the form of a one-pot-reaction without
isolation of the compounds A and B. It is also possible to add the whole amount of
halogenating agent at the beginning of the reaction, but preferably the halogenating agent
is added portionwise, for example in several portions of one equivalent each. The
mono-halogenation of the methyl g~roup R4 of compound B is preferably carried out in the
presence of a radical initiator.

form, are novel and also forrn a subject of the invention. Particularly preferred compounds

of a high-boiling aromatic hydrocarbon such as toluene, xylene, mesitylene or tetralin, and
at temperatures between 70C and 200C, in particular between 120C and 180C,

A further subject of the invention is the process for the preparation of the compounds of
the formula VII, in free form or in salt forrn, which comprises, for example,
f) reacting a compound of the forrnula
O COOH
R1--CF2~ ~ (vm),
CH (R3)n

acrylonitrile, preferably in a high-boiling polar solvent, such as acetonitrile, in the
presence of an acid anhydride, such as acetic anhydride, and at the reflux temperature of
the reaction mixture,
and, if desired, converting a compound of the formula VII which can be obtained
according tO the process or by a different route, in free form or in salt form, into a different
compound of the formula VII, resolving an isomer mixture which can be obtained
according to the process, and isolating ~he isomer desired, and/or converting a free
compound of the formula VII which can be obtained according to the process into a salt,
or converting a salt of a compound of the formula VII which can be obtained according to
the process into the free compound of the formula VII or into a different salt.
The compounds VIII are known or can be prepared analogously to corresponding known
compounds.
A compound I, II or VII which can be obtained according to the process or by a different
route can be converted into a different compound I, II or VII in a manner known per se by
replacing one or more substituents of the starting compound I, II or VII in the customary
manner by (an)other substituent(s) according to the invention.
For example,
- hydroxyl groups (as substituents of alkyl groups R4) can be alkylated to give alkoxy
groups (as substituents of alkyl groups R4);
- halogen R3 can be introduced into unsubsti~uted positions of the phenyl ring;
- mercapto groups R3 andJor R4 can be oxidised to give sulfinyl or sulfonyl groups R3
and~or R4 or sulfinyl groups R3 and/or R4 can be oxidised to give sulfonyl groups R3
2 ~ ~ 7
~ 15 ~
and/or R4;
- methyl g;oups R4 can be mono-halogenated to give mono-halomethyl groups 1~,; or
- the halogen substituent present in mono-halomethyl groups R4 can be replaced by an
alkoxy group to give a mono-a~coxymethyl group R4.
Depending on the choice of the reaction conditions and starting materials which are
suitable in each case, it is possible to replace, in one reaction step, only one substituent by
a different substituent according to the invention, or a plurality of substituents can be
replaced by other substituents according to the invention in the same reaction step.
Salts of compounds I, II or VII can be prepared in a manner known per se. For example,
acid addition salts of compounds I, II or VII are obtained by treatment with a suitable acid
or a suitable ion-exchanger reagent, and salts with bases are obtained by treatment with a
suitable base or a suitable ion-exchanger reagent.
Salts of compounds I, II or VII can be converted in the customary manner into the free
compounds I, II or VII, respectively, for example acid addition salts by treatment with a
suitable basic agent or a suitable ion-exchanger reagent and salts with bases for exarnple
by treatment with a suitable acid or a suitable ion-exchanger reagent.
Salts of compounds I, II or VII can be converted into other salts of compounds I, II or VII,
respectively, in a manner known per se, for example acid addition salts into different acid
addition salts, ~or example by treatment of a salt of an inorganic acid such as a
hydrochloride with a suitable metal salt such as a sodium salt, barium salt or silver salt, of
an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt
which forms, for example silver chloride, is insoluble and so precipitates from the reaction
mixture.
Depending on the procedure or reaction conditions, the compounds I, II or VII which have
salt-forming properties can be obtained in free form or in the form of salts.
The compounds I, II or VII, in free form or in salt form, can exist in the fo~n of one of the
isomers which are possible or as a mixture thereof, for example as pure isomers, such as
antipodes and/or diastereomers, or as isomer mixtures such as enantiomer mixtures, for
example racemates, diastereomer mixtures or racemate mixtures, depending, for exarnple,
on the number, absolute and relative configuration of asymmetric carbon atoms in the
2~ 7
16 -
molecule and/or depending on the configuration of non-aromatic double bonds in the
molecule; the invention relates to the pure isomers as well as to all isomer mixtures which
are possible and is to be understood accordingly llereinbefore and hereinafter, even when
stereochemical details are not mentioned specifically in each case.
Diastereomer m;xtures and racemate mixtures of compounds 1, II or VII, in free form or in
salt form, which can be obtained according to the process - depending on the choice of
starting materials and procedures - or by other routes can be resolved in the known manner
based on the physicochemical differences of the components to give the pure
diastereomers or racemates, for example by fractional crystallisation, distillation and/or
chromatography.
Enantiomer mixtures such as racemates which can be obtained accordingly can be
resolved by known methods to give the optical antipodes, for example by recrystallisation
from an optically active solvent, by chromatography on chiral adsorbents, for example
high-pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable
microorganisms, by cleavage with specific immobilised enzymes, via the formation of
inclusion compounds, for example using chiral crown ethers, where only one enantiomer
is sequestered, or by conversion into diastereomeric salts, for example by reacting a basic
end product racemate with an optically active acid such as carboxylic acid, for example
camphoric acid, tartaric acid or malic acid, or sulfonic acid, for example camphorsulfonic
acid, and resolution of the resulting diastereomer mixture, for example on the basis of
their different solubilities by fractional crystallisation to give the diastereomers from
which the enantiomer desired can be liberated by the action of suitable agents, for example
basic agents.
In addition to the resolution of corresponding isomer mixtures, pure diastereomers, or
enantiomers, can also be obtained according to the invention by generally known methods
of diastereoselective, or enantioselective, synthesis, for example by carrying out the
process according to the invention with educts having a suitable stereochemistry.
It is advantageous to isolate, or synthesise, in each case the biologically more active
isomer, for example enantiomer or diastereomer, or isomer mixture, for example
enantiomer mixture or diastereomer mixture, if the individual components have different
biological activities.

The compounds I, II or VII, in free form or in salt form, can also be obtained in the form
of their hydrates and/or can include other solvents, for example those which can be used
for the crystallisation of compounds in solid form.
The invention relates to all those embodiments of the process in which a compound which
can be obtained in any step of the process is used as starting material or interrnediate and
all, or some, of the missing steps are carried out, or in which a starting material in the form
of a derivative or salt and/or racemates or antipodes thereof are used or, in particular,
formed under the reaction conditions.
It is preferred to use those starting materials and intermediates, in each case in free form
or in salt forrn, in the process of the present invention which lead to the compounds I or
salts thereof which have been described at the outset as being particularly valuable.
In particular, the invention relates to the preparation processes described in Examples H1
to H6.
Another subject of the invention is novel starting materials and interrnediates, in each case
in free form or in salt form, which are used according to the invention for the preparation
of the compounds I or salts thereof, a process for their preparation, and their use as starting
materials and intermediates for the preparation of the compounds I; in particular, this
applies to the compounds II and VII.
The compounds I according to the invention are valuable active ingredients in the field of
pest control which have a very favourable biocidal spectrum when used preventively
and/or curatively, even at low application concentrations, while being well tolerated by
warm-blooded species, fish and plants. The active ingredients according to the invention
are active against all or individual development stages of norrnally sensitive, but also
resistant, animal pests such as insects and representatives from the order of the Acarina,
and of phytopathogenic fungi. The insecticidal and/or acaricidal action of the active
ingredients according to the invention can be demonstrated either directly, i.e. in
destruction of the pests, which is immediately effective or only after some time has
elapsed, for example during moulting, or indirectly, for example by reduced oviposition
and/or hatching rate, good action meaning a destruction rate (mortality) of at least 50 to
60%.

especially on useful plants and ornamentals in agriculture, in horticulture and in forestry,
or on parts of such plants, such as *uits, flowers, foliage, staL~cs, tubers or roots, and in

Other fields of application of the active ingredients according to the invention are the
protection of stored products and stores and of material, and, in the hygiene sector, in
particular the protection of domestic animals and productive livestock against pests of the
abovementioned type.
The invention therefore also relates to pesticides such as emulsifiable concentrates,
suspension concentrates, directly sprayable or dilutable solutions, spreadable pastes, dilute
emulsions, wettable powders, soluble powders, dispersible powders, dusts, granules or
encapsulations in polymeric substances, which comprise - at least - one of the active
ingredients according to the invention and which are to be selected depending on the
intended aims and prevailing circumstances.
The active ingredient in these compositions is employed as pure active ingredient, for
example a solid active ingredient in a specific particle size, or, preferably, together with -
at least - one of the auxiliaries conventionally used in the art of formulation, such as
extenders, for example solvents or solid carriers, or surface-active compounds
(surfactants).
The following are possible as solvents: aromatic hydrocarbons which may be partially
hydrogenated, preferably the fractions C8 to Cl2 of alkylbenzenes, such as xylene
mixtures, alkylated naphthalenes or tetrahydronaphthalenes, aliphatic or cycloaliphatic
hydrocarbons such as paraffins or cyclohexane, alcohols such as ethanol, propanol or
butanol, glycols as well as their ethers and esters such as propylene glycol, dipropylene
glycol ether, ethylene glycol or ethylene glycol monomethyl ether or ethylene glycol
monoethyl ether, ketones such as cyclohexanone, isophorone or diacetone alcohol,strongly polar solvents such as N-methyl-pyrrolid-2-one, dimethyl sulfoxide or
N,N-dimethylformamide, water, unepoxidised or epoxidised vegetable oils such as
unepoxidised or epoxidised rapeseed oil, cas~or oil, coconut oil or soya oil, and silicone
oils.
Solid carriers which are generally used, for example for dusts and dispersible powders, are
ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To
improve the physical properties, it is also possible to add highly-disperse silica or
s7
- 22 -
highly-disperse absorptive polymers Possible particulate adsorptive carriers for granules
are either porous types, for example pumice, brick glit, sepiolite or bentonite, or
non-sorptive carrier materials, for example calcite or sand. Moreover, a large number of
pregranulated materials of inorganic or organic nature can be used, in particular dolomite
or comminuted plant residues.
Suitable surface-active compounds are non-ionic, cationic andlor anionic surfactants or
surfactant mixtures having good emulsifying, dispersing and wetting properties,
depending on the nature of the active ingredient to be forrnulated. The surfactants listed
below are only exemplary; a large number of other surfactants which are customarily used
in the art of the formulalion and suitable according to the invention are described in the
specialist literature.
Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or
cycloaliphatic alcohols, saturated or unsaturated fatty acids and aL~ylphenols, which can
contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic)
hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols.
Other suitable non-ionic surfactants are water-soluble polyethylene oxide adducts with
polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropyleneglycol which have 1 to 10 carbon atoms in the alkyl chain and contain 20 to 250 ethylene
glycol ether groups and 10 to 100 propylene glycol ether groups. I he compounds
mentioned generally contain 1 to 5 ethylene glycol units per propylene glycol unit.
Examples which may be mentioned are nonylphenol polyethoxyethanols, castor oil
polyglycol ethers, polypropylene/polyethylene oxide adducts,
tributylphenoxypolyethoxyethanol, polyethylene glycol and
octylphenoxypolyethoxyethanol. Other suitable substances are fatty acid esters of
polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.
The cationic surfactants are mainly quaternary ammonium salts which contain at least one
alkyl radical having 8 to 22 C atoms as substituents and which have lower halogenated or
free alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. The salts are
preferably in the form of halides, methylsulfates or ethylsulfates. Examples which may be
mentioned are stearyltrimethylammonium chloride and
benzyldi(2-chloroethyl)ethylammonium bromide.
Suitable anionic surfactants can be either water-soluble soaps or water-soluble synthetic
surface-active compounds. Suitable soaps which may be mentioned are the alkali metal
salts, alkaline earth metal salts and substituted or unsubstituted ammonium salts of higher
fatty acids (Cl0-C22), such as the sodium salts or potassium salts of oleic or stearic acid or
of nat~lral mixtures of fatty acids which can be oblained, for example, from coconut oil or
tallow oil; fatty acid methyltaurides may furtherrnore be mentioned. However, synthetic
surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates,
sulfonated benzimidazole derivatives or alkylaryl sulfonates. The fatty sulfonates and fatty
sulfates are generally in the form of alkali metal salts, alkaline earth metal salts or
substituted or unsubstituted ammonium salts and generally have an alkyl radical having 8
to 22 C atoms, alkyl also embracing the alkyl moiety of acyl radicals; exarnples which
may be mentioned are the sodium or the calcium salt of ligninsulfonic acid, of the
dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture prepared from natural fatty
acids. This group also includes the salts of the sulfuric acid esters and sulfonic acids of
fatty alcohoVethylene oxide adducts. The sulfonated benzimidazole derivatives preferably
contain 2 sulfonyl groups and one fat~ acid radical having 8 to 22 C atoms. Examples of
alkylaryl sulfonates are the sodium, calcium or triethanolammonium salts of
dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a
naphthalenesulfonic acid/formaldehyde condensation product. Other suitable compounds
are corresponding phosphates, for example salts of the phosphoric acid ester of a
p-nonylphenol/(4- 14)ethylene oxide adduct, or phospholipids.
As a rule, the compositions comprise 0.1 to 99 %, in particular 0.1 to 95 %, of active
ingredient and 1 to 99.9 %, in particular 5 to 99.9 %, of - at least - one solid or liquid
auxiliary, where, as a rule, 0 to 25 %, in particular 0.1 to 20 %, of the composition can be
surfactants (% is in each case to be understood as meaning per cent by weight). While
concentrated compositions are more preferred as commercially available goods, the end
consumer generally uses dilute compositions which have considerably lower
concentrations of active ingredient. In particular, preferred compositions are composed as
follows (% = per cent by weight):
Emulsifiable concentrates:
Active ingredient: 1 to 90 %, preferably 5 to 20 %
Surfactant: 1 to 30 %, preferably 10 to 2û%

The activity of the compositions according to the invention can be broadened considerably
and adapted to prevailing circumstances by adding other insecticidal, acaricidal and/or
fungicidal active ingredients. Suitable examples of active ingredients which are added are
representatives of the following classes of active ingredients: organophosphoruscompounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids,
chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions
according to the invention can also comprise further solid or liquid auxiliaries, such as
stabilisers, for example epoxidised or unepoxidised vegetable oils (for example epoxidised
coconut oil, rapeseed oil or soya oil), defoamers, for example silicone oil, preservatives,
viscosity regulators, binders andlor adhesives, and also fertilisers or other active
ingredients for achieving specific effects, for example bactericides, nematicides,
molluscicides or selective herbicides.
The compositions according to the invention are prepared in a manner known per se, for
example in the absence of auxiliaries by grinding and/or screening of a solid active
ingredient, or mixture of active ingredients, for example to obtain a certain particle size,
and in the presence of at least one auxiliary for example by intimately rnixing and/or
grinding the active ingredient, or mixture of active ingredients, with the auxiliary(ies).

These processes for the preparation of the compositions according to the invention and the
use of the compounds I for the preparation of these compositions are also part of the
invention.
The invention furthermore relates to the methods by which the compositions are applied,
i.e. the methods for controlling pests of the abovementioned type, such as spraying,
atomising, dusting, brushing on, dressing, scattering or pouring, to be selected depending
on the intended aims and the prevailing circumstances, and to the use of the compositions
for controlling pests of the abovemen~ioned type. Typical application concentrations are
between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The
application rates per hectare are generally 1 to 2000 g of active ingredient per hectare, in
particular 10 to 1000 g/ha, preferably 20 to 600 g/ha.
A preferred application method in the field of crop protection is application to the foliage
of the plants (foliar appiication), where the ~requency of application and the dosage rate
can be adjusted as a function of the severity of infestation with the pest in question.
Alternatively, the active ingredient can reach the plants via the root system (systemic
action), by allowing the locus of the plants to absorb a liquid composition or by
incorporating the active ingredient in solid forrn into the locus of the plants, for exarnple
the soil, such as in the form of granules (soil application). In the case of paddy rice, such
granules can be metered into the flooded paddy field.
The compositions according to the invention are also suitable for protecting plant
propagation material, for exarnple seeds, such as fruits, tubers or grains, or plant cuttings,
against fungal infections and animal pests. The propagation material can be treated with
the composition before use, for example seed can be dressed before sowing. The active
ingredients according to the invention can also be applied to seed kernels (coating) either
by immersing the kernels in a liquid composition or by coating them with a solidcomposition. It is also possible to apply the cornposition to the site where the propagation
material is used, for example during sowing into the seed furrow. The invention also
relates to these treatment methods for plant propagation material and to the plant
propagation material which has been treated in this manner.
The following examples are intended to illustrate the invention. They impose no limitation
on the invention. Temperatures are given in degrees centigrade.

Preparation examples
Example H1: 2-(4-Chlorophenyl)-3-cya~o-5-pentafluoroethyl-pyrrole (Table 2,
Compound No. 2.1).
CN
F3C--CF2~ ~CI
A mixture of 47 g of 4-(4-chlorophenyl)-2,5-dihydro-5-oxo-2-pentafluoroethyl-oxazole,
131.1 g of 2-chloroacrylonitrile and 750 ml of nitromethane is refluxed for 22 hours and
then cooled to approx. +5. The solid which has precipitated is filtered off and washed
with a little cold dichloroethane. This gives, if desired with additional working up of the
mother liquor, the title compound which melts at 223.5 to 224.
Example H2: 4-Bromo-2-(4-chlorophenyl)-3-cyano-5-pentafluoroethyl-pyrrole (Table 1,
CompoundNo. 1.1).

20 g of 2-(4-chlorophenyl)-3-cyano-S-pentafluoroethyl-pyrrole and 12.8 g of sodium
acetate are introduced into 400 ml of acetic acid. The mixture is stirred for lS minutes (a
clear solution forms~, treated dropwise in the course of 1 hour at room temperature with a
solution of 49.8 g of bromine in 100 ml of acetic acid, stirred for 2 hours at room
temperature, poured into 2 l of sodium hydrogen sulfite solution (10 %) and filtered. The
colourless crystals obtained are washed with water and dried in vacuo at +50. This gives
the title compound which melts at 213 to 215 with decomposi~ion.
Example H3: 4-Bromo-2-(4-chlorophenyl)-3-cyano-1-ethoxymethyl-
S-pentafluoroethyl-pyrrole (Table 1, Compound No. 1.3).

50 rnl of dry tetrahydrofuran, and the solution is treated with 2.7 g of potassium
tert-butanolate at room ~emperature. 2.7 g of chloromethyl ethyl ether are subsequently
added dropwise. The reaction mixture is stirred for 22 hours at room temperature, poured
into 400 ml of water and extracted three times with diethyl ether. The organic phases are
combined, wasl~ed with NaCI solution, dried over Na2SO4 and evaporated in vacuo. The
result is yellow crystals ~hich are recrystallised from 10 ml of hexane. This gives the title
compound which melts at 69 to 70.5".

A mixture of 15 g of N-c~rboxy-4-chlorophenyl-methyl-N-methyl-N-pentafluoroethyl-
carbonyl-amine, 100 ml of acetonitrile, 4.2 ml of acrylonitrile, 11 g of acetic anhydride
and 15 drops of triethylamine is heated under reflux for 5.5 hours and then evaporated to
dryness. Purification of the residue by column chromatography [SiO2; hexane/ethyl
acetate (9:1)] yields the title compound, which melts at 113 to 116.

A saturated solution of 12 g of N-chlorosuccinimide in N,N-dimethylformamide is added
over a period of 30 minutes to a mixture of 10 g of 2-(4-chlorophenyl)-3-cyano-
4,5-dihydro-1-methyl-5-pentafluoroethyl-pyrrole and 10 ml of N,N-dimethylformamide.
The reaction mixture is heated to 100 for 30 minutes and is then poured, while stilTing,
into 1 1 of water. The oily precipitate is taken up in ethyl acetate, and the ethyl acetate
phase is washed several times with water, dried and evaporated to dryness.
Recrystallisation of the residue using ethyl acetate/hexane yields the title compound,
which melts at 120.
