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 iminopyrrolidinylindoles 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.
