The compounds are of the heterocyclic class of 2-phenethylpiperidines having an amido substituent in the ortho position of the phenethyl moiety. Substituents in the ortho position include formamido, benzamido, cinnamamido, 2-thiophenecarboxamido, alkanesulfonamido and alkanoylamido. They are useful as antiarrhythmic and/or antiserotonin agents. The novel compounds are prepared by reaction of appropriately substituted o-aminophenethylpiperidines and the carbonyl or sulfonyl halides or anhydrides. Typical embodiments of this invention are 4-methoxy-2'-[2-(1-methyl-2-piperidyl)ethyl]benzanilide and 2'-[2-(1-methyl-2-piperidyl)ethyl]cinnamanilide.
这些化合物属于异环类2-苯乙基哌啶,其在苯乙基部分的邻位具有酰胺取代基。邻位的取代基包括甲酰胺基、苯甲酰胺基、肉桂酰胺基、2-噻吩羧酰胺基、烷磺酰胺基和烷酰胺基。它们可用作抗心律失常和/或抗5-羟色胺药物。这些新化合物是通过适当取代的o-氨基苯乙基哌啶与羰基或磺酰卤或酐的反应制备的。本发明的典型实施例包括4-甲氧基-2'-[2-(1-甲基-2-哌啶基)乙基]苯甲酰胺和2'-[2-(1-甲基-2-哌啶基)乙基]肉桂酰胺。
