実験手順

To a solution of 0.035 g (0.09 mmol) (6-chloro-1H-indol-3-yl)-[4-(2-methoxy-phenyl)-piperidin-1-yl]-methanone in 2 ml N,N-dimethylformamide were added 0.005 g (0.10 mmol) sodium hydride (50% in oil). After 45′, 0.008 ml (0.10 mmol) methanesulfonyl chloride were added. The reaction mixture was quenched with water after 3 h and extracted with ethyl acetate (2×50 ml). The combined organic layers were washed with water (2×30 ml) and brine (1×30), dried over sodium sulfate and concentrated to dryness. The residue was chromatographed (loaded as a solution in toluene; Flashpac 5 g; n-heptane/ethyl acetate 100:0→75:25) to give the title compound (0.007 g; 17%) as a light yellow solid.
