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-1-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 arranged to provide iminopyrrolinidinylindoles 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.
已发现具有利尿、抗血栓、平滑肌松弛、抗炎和抗心律失常性质的N-苯基酰胺。它们是通过在磷酸氧氯化物存在下,将取代的苯胺与选自酰胺和内酰胺组的羧酰胺反应制备而成。因此获得的取代N-苯基酰胺的典型示例包括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-1-基-p-甲氧苯胺基)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。吲哚取代的N-苯基酰胺可以排列成为有用的利尿、抗血栓和平滑肌松弛剂的亚胺吡咯烷基吲哚。在3-[(N-1-吡咯烷-2-基-p-甲氧苯胺基)甲基]吲哚的情况下,重新排列的产物是3-[[2-p-甲氧基苯基亚氨基)-1-吡咯烷基]甲基]吲哚。
