A mixture of 1-benzenesulfonyl-2-(oxazol-2-yl)-5-methanesulfonyl-1H-pyrrolo[2,3-b]pyridine (0.359 g), potassium hydroxide (0.34 g) and methanol (30 ml) was stirred at 15 to 30° C. for 30 minutes. To the reaction mixture was added water, the resulting 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 1:1) to obtain 0.19 g of the desired product.
