실험 절차

To a solution of 1-[(1-methylpiperidin-3-yl)methyl]piperazine (400 mg) in chloroform (10 ml) was added a 2M solution of sodium(trimethylsilyl)amide in THF (2.2 ml). The resulting solution was stirred at room temperature for 10 minutes. 3,4-Dichlorophenylisothiocyanate (0.44 ml) was added and mixture stirred at room temperature for 1 hour. The reaction was quench with water (1 ml) then concentrated in vacuo before being separated between ethyl acetate (100 ml) and saturated sodium bicarbonate solution (100 ml). The ethyl acetate layer was separated, dried over magnesium sulphate, filtered then concentrated in vacuo onto silica gel (1.0 g). The resulting powder was purified by column chromatography on silica gel (50 g) using a gradient of 100% dichloromethane through to 10% methanolic ammonia in dichloromethane to give the title compound (726 mg).
