Procedure

A mixture of 1-benzenesulfonyl-2-(oxazol-2-yl)-5-methylthio-1H-pyrrolo[2,3-b]pyridine (28 mg), magnesium monoperoxyphtalate hexahydrate (116 mg, 80% purity), dichloromethane (1.2 ml) and methanol (0.5 ml) was stirred at 0° C. for 30 minutes. To the reaction mixture was added a saturated aqueous sodium hydrogencarbonate solution, and the mixture was extracted with dichloromethane, washed with a saturated aqueous NaCl solution, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography (hexane:ethyl acetate=1:3) to obtain 14 mg of the desired product.
