실험 절차

A mixture of 4.5 parts of 1-(2-chloroethyl)-2,3-dihydro-1H-benzimidazol-2-one, 5 parts of 1-(diphenylmethyl)piperazine, 6.4 parts of sodium carbonate and 200 parts of 4-methyl-2-pentanone is stirred and refluxed overnight with water-separator. The reaction mixture is cooled and water is added. The precipitated product is filtered off and crystallized from a mixture of N,N-dimethylformamide and water, yielding 1-{2-[4-(diphenylmethyl)-1-piperazinyl]ethyl}-1,3-dihydro-2H-benzimidazol-2-one; mp. 218° C.
