Synthesis of new psychotropic 2-imidazolidinones

The report describes the synthesis and pharmacology of some new derivatives of 1-(m or p-chlorophenyl)-2-imidazolidinone. These compounds were obtained either by reacting an amine with an N-(2-chloroethyl)-2-imidazolidinone or by reacting a 2-chloroethylamine with an N-substituted-2-imidazolidinone. Two compounds (II f, h) showed interesting psychotropic activity.
