실험 절차

A solution of 4-chlorophenylsulphonyl chloride (1.78 g) in methylene chloride (10 ml) was added dropwise over 15 minutes to a mixture of 4-[1-(2-methylpyrimidin-4-yl)piperazine-4-ylmethyl]piperidine trihydrochloride (2.78 g) and triethylamine (6.72 ml) in dichloromethane (40 ml) at 0° C. The solution was stirred at ambient temperature for 18 hours. The solution was diluted with dichloromethane and washed with water, dried (Na2SO4) and evaporated. The residue was purified by chromatography eluting with 4% methanol in dichloromethane. Recrystallisation from ethyl acetate/hexane gave, as a solid 1-(4-chlorophenylsulphonyl)-4-[1-(2-methylpyrimidin-4-yl)piperazin-4ylmethyl]piperidine (2.50 g), mp 191-193° C. (decomp.).
