実験手順

To a solution of 2-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridine (200 mg) in tetrahydrofuran (5 mL) was added N-chlorosuccinimide (61.2 mg) at 0° C., and the mixture was stirred overnight at room temperature, and further at 50° C. for 1 day. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate, and washed with saturated aqueous sodium hydrogen carbonate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (49.0 mg, yield 23%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate-hexane (2:1, volume ratio). MS: 471 (MH+).
