摘要

Improvements to the subject matter of patent of invention no. 541,911 relating to Process for obtaining new α- (alkylaminopropionyl)-thiophen derivatives substituted in the thiophen ring comprises reacting α (bromopropionyl)-thiophens of general formula II' with amines of general formula III', thus obtaining the new α-(alkylaminopropionyl)-thiophen derivatives substituted in the thiophen ring of general formula I' where X' is a radical other than hydrogen, preferably methyl or chlorine, and R' is a straight or branched alkyl radical, which can form pharmaceutically acceptable salts by treatment with corresponding acids. Having pharmacological application through its antidepressant effect. IMAGE
