  ChEBI: An N-alkylpiperazine carrying (4-chlorophenyl)(phenyl)methyl and 4-tert-butylbenzyl groups.

• Manufacturing Process

  1 mol 4-chlorobenzhydril chloride was heated in toluene to reflux with 1 mol ethyl ester of piperazine 1-carboxylic acid at about 150°C in a presence of an excess of triethyl amine. On cooling the triethyl amine hydrochloride was filtered off, a solvent was removed in vacuum and the residue [(4-chlorophenyl)- phenyl-methyl]piperazine carboxylic acid ethyl ester was boiled straight away with potassium hydroxide in ethanol for 48 hours. After removing ethanol in vacuum to dryness, the residue was dissolved in benzene and washed with water. The benzene solution was dried, benzene removed in vacuum. The residue was distilled to give 4-chlorobezhydryl-piperazine. It had given the desired 1-(p-tert-butylbenzyl)-4-(p-chloro-α-phenylbenzyl)- piperazine, buclizine, by a reaction with 4-tert-butylbenzyl chloride in the presence of any halogen hydrochloride acceptor (triethyl amine, sodium or potassium carbonate and so on). The obtained product had BP: 230°- 240°C/0.001 mm Hg.
