Reaction Steps

To a solution of 0.423 part of N1 -(morpholinocarbonylmethyl)-N4 -(2-amino-3,5-dibromobenzyl)piperazine in 4 volume parts of pyridine is added 0.25 part of benzoylchloride, and the mixture is kept standing overnight at room temperature. The solvent is distilled off, and residue is chromatographed over alumina. Ethyl acetate eluates gives oily substance. The resultant oily substance is treated with ethanolic hydrochloric acid, and to the resultant is added isopropyl ether to give N1 -morpholinocarbonylmethyl-N4 -(2-monobenzoylamino-3,5-dibromobenzyl)piperazine hydrochloride melting at 162° to 164° C.
