A reaction of 1-cinnamylpiperazine (III) with chloroacetyl gave the chloroacetyl derivative IV which was subjected to substitution reactions with aniline, 4-phenylpiperidin-4-ol (XIa),4-(4-fluorophenyl)piperidin-4-ol (XIb) and 4-(4-chloro-3-trifluoromethyl)piperidin-4-ol and afforded the title compounds V and VII-IX. Acylation reactions of compounds V and VII with propionyl chloride gave the propionanilide derivative VI and the 4-phenyl-4-propanoyloxypiperidine derivative X. With the exception of compound VIII, the new substances are analgetically less active than 1-butyryl-4-cinnamylpiperazine (I) and as antiinflammatory agents they are little active or inactive.
1-肉桂基哌嗪(III)与氯乙酰反应得到氯乙酰衍生物IV,然后与苯胺、4-苯基哌啶-4-醇(XIa)、4-(4-氟苯基)哌啶-4-醇(XIb)和4-(4-氯-3-三氟甲基)哌啶-4-醇发生取代反应,得到标题化合物V和VII-IX。化合物V和VII与丙酰氯发生酰化反应,得到丙酰苯胺衍生物VI和4-苯基-4-丙酰氧基哌啶衍生物X。除化合物VIII外,新物质的镇痛活性均低于1-丁酰基-4-肉桂基哌嗪(I),作为抗炎药物,它们的活性较低或无活性。
