Cyclic amine derivotlve~ ;
This inventlon relates to certa:ln novel cyclic
amlne derivatlve~, to pharmaceutical compos1tion~
con~alning them and to proce~se~s for .their preparation. -:~
Canadian Patent Nb. n ,086,726 describes, inter alia~ ;the c~mpound
of formula
~ :
~ ~ ~CH2CH2CH2- N - CH2CH2 ~ 0CH3
and the physiologic~lly ~ccept~ble acid aadition :~
salts thereof, which has valuable pharmacological
propertie~, namely a mild hypotensive activlty
and, more particuIarly, a selective heart rate ''` '~
lowering aotlvlty.
Surpri~ingly, it has now:been found that certain ; ~
new cycllc ~mine d~rivatives have even more valuable ; ~ ~;
pharmacological propertie~, particularly a hypo~ensive
ef~ect ~nd ~ long-l~sting heart rate lowering actlvlty ...
and the effect of reduclng ~he 2 requlrement of
~he heart.
Thus in one n~pect the present lnventlon provlde~

Since they have at least one chiral centre, the -
compounds of formula I obtained can be resolved
by conventional methods into their diastereomers,
for example by column chromatography, and into
their enantiomers, for example by column chromatography
on a chiral phase or by crystallisation with optically
active acids, e.g. with D- or L-monomethyl tartaric
acid, D- or L-diacetyl tartaric acid, D- or L-tartaric
acid, D- or L-lactic acid or D- or L-camphoric
acid.

acids include, for example, hydrochloric, hydrobromic,
sulphuric, phosphoric, acetic, lactic, citric,
tartaric, succinic, maleic ancl fumaric acids.
The compounds of formulae Il to VIII used as starting
materials are known from the literature in some
cases or may be obtained using methods known Per
se.

Thus, for example, a starting compound of formula

imino compound of formula IV with a cyclic amine
protected at the N atom by a conventional prot~cting
groupl said cyclic amine being substituted in the ;
carbon structure by an alkyl group which is in i`~
turn substituted in the terminal position by a
nucleophilic leaving group, and subsequently cleaving
the protecting group used. The cyclic amine required
for this reaction may be obtained by converting
a corresponding cyclic amine substituted by a hydroxyalkyl
group into a suitable halogen- or sulphonic acid
ester derivative thereofl and the imino compound
of formula IV required for this reaction may be
obtained by cyclising a corresponding compound,
e.g. by cyclising a compound of formula IX

yl)-ethyl~-piperid-3-Yl)-methYl]-7,8-dimethoxv-
2-oxo-1,3,4,5-tetrahYdro-2H-3-benzazePine-hYdrochloride
Composition:
1 tablet contains:
Active substance 7.5 mg
Corn starch 59.5 mg
Lactose 48.0 mg
Polyvinylpyrrolidone 4.0 mg
Magnesium stearate 1.0 mq ~ -
120.0 mg
Method of preParation
The active substance, corn starch, lactose and
polyvinylpyrrolidone are mixed together and moistened
with water. The moist mixture is pushed through
a screen with a mesh size of 1.5 mm and dried at
about 45C. The dry granulate is passed through
a 1.0 mm mesh screen and mixed with magnesium stearate.
The final mixture is compressed in a tablet press
with dies 7 mm in diameter provided with a dividing
notch to form tablets each weighing 120 mg.

Method of Preparation
The active substance, corn starch, lactose and
polyvinylpyrrolidone are throughly mixed and moistened
with water. The moist mass is forced througb a
1 mm screen, dried at about 45C and then the granulate
is passed through the same screen. After magnesium
stearate has been adaed~ convex tablet cores with r
a diameter of 6 mm are compressed in a tablet making
machine. The tablet cores thus produced are coated ~-
in known manner with a coating consisting essentially
of sugar and talc. The fin$shed coated tablets
are polished with wax and the weight of the final
coated tablet is 130 mg.

Method of Preparation
. ~.
In a suitable mixing vessel the active substance
is dissolved in water for injec~ions and the solution
is made isotonic with sorbitol,
After being filtered through a diaphragm filter -~
the solution is transferred under a current of
N2 into purified and æterilized ampoules and auto-
claved for 20 minutes in a jet of steam.
