Abstract

A method for the preparation of 3,4-diethyl-1 (3 (4- (m-chlorophenyl) -1-piperazinyl) -propyl-1,2,4-triazol-5-one, which consists of heating during 5 hours an equi molecular mixture of 4- (N-chlorophenyl) -1-piperazine propanol and 3,4-diethyl-1,2,4-triazol-5-one in the presence of the appropriate amount of toluene of 1.1 equivalents of dicycloxycarbodiimide and 1/40 mol of cuprous salt, in diluting with benzene, filtering the dicyclohexylurea, in chromatographing the crude base and in dissolving the pure fractions in benzene and transforming them into hydrochloride.
