実験手順
120 mg of 1-[(2-methoxy-3-pyridyl)methyl]-4-[2-(2-aminophenyl)-2-oxoethyl]piperidine obtained in Example 64, 0.1 ml of triethylamine and 0.041 ml of methanesulfonyl chloride were dissolved in 2 ml of dichloromethane, and the mixture was stirred for 2 hours under ice-cooling. An aqueous sodium bicarbonate was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the crude product was purified by silica gel column chromatography (ethyl acetate), to give 90 mg of the title compound as a yellow oil.
