実験手順

A mixture of 4-{[4-(4-Phenyl-piperazine-1-carbonyl)-phenylamino]-methyl}-benzonitrile (50 mg, 0.13 mmol), phenylsulfonylchloride (80 mg, 0.42 mmol) and pyridine (0.04 mL, 0.44 mmol) in dichloromethane (5 ml) was heated to reflux for 16 hours. The reaction mixture was cooled to room temperature and the quenched by the addition of water (4 ml). The organics were collected, dried over magnesium sulfate and concentrated in vacuo The residue was purified by preparative thin layer chromatography (dichloromethane/ethyl acetate 1:1) to afford the title compound as a white solid (16.4 mg, 27% yield). HPLC retention time 6.71 min. Mass spectrum (ES+) m/z 475 (M+H).
