Procedure

To a solution of N-methyl-N-{2-[5-(2-oxo-2-thiomorpholinoethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}thiophene-2-sulfonamide (560 mg) in tetrahydrofuran (15 mL), ethanol (5 mL) and water (5 mL) was added OXONE (registered trade mark, 986 mg) at room temperature, and the mixture was stirred for 1 hr. Sodium sulfite (3 g) was added to the reaction mixture, and the mixture was stirred for 10 min. Water was added, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The obtained residue was subjected to silica gel column chromatography to give the title compound (242 mg, yield 44%) as white crystals from a fraction eluted with ethyl acetate. melting point 158° C.
