New 4 - (4 - cinnamoyl - 1 - piperidino) butyrophenones, particularly useful as antipsychotic agents, and their method of preparation

摘要

Cinnamoylpiperidinobutyrophenone derivatives and pharmaceutically acceptable salts thereof of the following general structure: IMAGE wherein R is hydrogen, alkyl, alkoxy, halogen or trifluoromethyl; and R' is hydrogen or halogen; are useful as antipsychotic agents. The novel compounds are produced by aldol condensation of a benzaldehyde with a protected 4-(4-acetyl-1-piperidino)-butyrophenone.
