N-Phenyl amidines which have diuretic, antithrombogenic, smooth muscle relaxant, anti-inflammatory and antiarrhythmic properties have been discovered. They are prepared by reacting a substituted aniline with a carboxamide selected from the group consisting of amides and lactams in the presence of phosphorus oxychloride. Typical examples of substituted N-phenyl amidines thus obtained are 5-methyl-2-(N-phenylbenzylamino)-1-pyrroline, 2-(N-phenylbenzylamino)-1-pyrroline, 3-[(N-1-pyrrolin-]-yl-p-anisidino)methyl]indole and 4,5,6,7,8,9-hexahydro-2-(N-phenylphenethylamino)-3H-azonine. Indole substituted N-phenyl amidines can be rearranged to provide iminopyrrolinidinyl-indoles which are useful as diuretic, antithrombogenic and smooth muscle relaxant agents. In the case of 3-[(N-1-pyrrolin-2-yl-p-anisidino)methyl]indole, the rearranged product is 3-[[2-(p-methoxyphenylimino)-1-pyrrolidinyl]methyl]indole.
已经发现了具有利尿、抗血栓、平滑肌松弛、抗炎和抗心律失常性质的N-苯基甲酰胺,它们是通过在三氯化磷存在下将取代苯胺与来自包括酰胺和内酰胺的群体中选择的羧酰胺反应制备而成。因此获得的取代N-苯基甲酰胺的典型例子包括5-甲基-2-(N-苯基苄氨基)-1-吡咯烷,2-(N-苯基苄氨基)-1-吡咯烷,3-[(N-1-吡咯烷-2-基)-p-甲氧基苯氨基甲基]吲哚和4,5,6,7,8,9-六氢-2-(N-苯基苯乙基氨基)-3H-氮杂环己烷。吲哚取代的N-苯基甲酰胺可以重排以提供亚胺吡咯啉基吲哚,它们可用作利尿、抗血栓和平滑肌松弛剂。在3-[(N-1-吡咯烷-2-基)-p-甲氧基苯氨基甲基]吲哚的情况下,重排产物是3-[[2-(对甲氧基苯基亚胺)-1-吡咯烷基]甲基]吲哚。
