実験手順

To a solution of 4-[[4-methoxybenzenesulfonyl](benzyl)amino]-4-[carbomethoxy]piperidine (1.0 g, 2.39 mmol) in dimethylformamide (160 mL) is added sodium hydride (287.0 mg, 7.18 mmol, 60% in oil) at 0° C., followed by benzyl bromide (450.0 mg, 2.63 mmol). The reaction mixture is slowly warmed to room temperature and stirred overnight. The mixture is quenched with water and extracted with ethyl acetate. The combined organic layers are washed with brine, dried (Na2SO4) and the solvent is evaporated to give 4-[[4-methoxybenzenesulfonyl](benzyl)amino]-1-[benzyl]-4-[carbomethoxy]-piperidine.
