Procedure
To methylene chloride (15 ml) of the 3-[(4-chlorophenylsulfonyl)-(2,5-difluorophenyl)methyl]pyridine (162 mg, 0.427 mmol) obtained in Example 19 was added 3-chloroperbenzoic acid (81 mg, 0.47 mmol). The resulting mixture was stirred for 24 hours. The reaction mixture was diluted with ether (60 ml). The diluted mixture was washed with a saturated aqueous solution of sodium bicarbonate, water and brine, dried and filtered. The filtrate was concentrated under reduced pressure to give a residue. The resulting residue was subjected to silica gel chromatography (ethyl acetate) to give the title compound (68 mg, 40%). The compound was crystallized from ethanol to afford colorless needle crystals.
