ABREGE DESCRIPTIF
L'invention concerne la préparation de dérivés
cinnamamides substitués représentés par la formule
< IMG >
dans laquelle R est l'hydrogène ou un halogène, R1 et R2
forment avec l'atome d'azote adjacent le groupe diméthyl-2,2
oxazolidinyl-3, selon laquelle on condense dans un premier
temps, l'éthanolamine sur l'acétone, puis on fait réagir un
chlorure de cinnamoyle sur l'oxazolidine intermédiaire. Ces
produits sont des composés intermédiaires de synthèse et
sont également efficaces en tant que myorelaxants au même
titre que les hydroxyalkylcinnamides.
