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-2-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 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-pyrrolindinyl]methyl]indole.
具有利尿、抗血栓形成、平滑肌松弛、抗炎和抗心律失常特性的N-苯基脒类化合物已被发现。它们是通过在磷酰氯存在下,将取代的苯胺与选自酰胺和内酰胺类的羧酰胺反应制备的。由此获得的典型取代N-苯基脒类化合物的例子包括5-甲基-2-(N-苯基苄氨基)-1-吡咯啉、2-(N-苯基苄氨基)-1-吡咯啉、3-[(N-1-吡咯啉-2-基-对甲氧基苯氨基)甲基]吲哚和4,5,6,7,8,9-六氢-2-(N-苯基苯乙氨基)-3H-氮杂萘。取代吲哚的N-苯基脒类化合物可以重排,提供作为利尿剂、抗血栓形成剂和松弛平滑肌剂有用的iminopyrrolinidinylindoles。对于3-[(N-1-吡咯啉-2-基-对甲氧基苯氨基)甲基]吲哚,重排产物是3-[[2-(对甲氧基苯亚氨基)-1-吡咯啉并[d]吲哚]甲基]吲哚。
