실험 절차

2.18 g of 4-chlorobenzylpiperazine are dissolved in 40 ml of absolute tetrahydrofuran. With stirring, 1.73 g of Hunig base and 2.64 g of 4-chloroacetylaminobenzoic acid chloride are added thereto in succession. The internal temperature rises to approximately 38°. After 30 minutes, the solution is concentrated by evaporation. The oily residue is digested with water, yielding 1-[4-(N-chloroacetylamino)benzoyl]-4-(4-chlorobenzyl)piperazine having a melting point of 205°-207°.
