To a solution of N-{5-[(1S)-2-methoxy-1-methylethoxy]-2-[5-(thiomorpholinomethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylpyridine-2-sulfonamide (80 mg) in dichloromethane (2 mL) was added m-chloroperbenzoic acid (16 mg) under ice-cooling, and the mixture was stirred for 30 min. Aqueous sodium thiosulfate solution was added, and the mixture was diluted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was recrystallized (acetone-hexane-diisopropyl ether) to give the title compound (37.5 mg, yield 46%) as a colorless solid. melting point 175-176° C.
