Abstract

Methods have been developed for dehydrating the unusually stable intermediate products of the Hantzsch reaction of N,N'-diphenylthioureas with derivatives of phenylchloropyruvic acid, viz. 4-hydroxy-4-methoxy(diethylamino)carbonyl-3,5-diphenyl-2-phenyliminothiazolidines, into the corresponding 4-methoxy(diethylamino)carbonyl-3,5-diphenyl-2-phenyliminothiazolines. Characteristic features of the dissociative ionization of the latter and their anilide analog under the action of electron impact have been clarified.
