Reaction Steps

A mixture of 1-benzenesulfonyl-2-trimethylsilyl-5-methylthio-1H-pyrrolo[2,3-b]pyridine obtained in Example 33 (1) (0.60 g), tetrabutylammonium fluoride/tetrahydrofuran solution (1.0 M, 0.8 ml) and tetrahydrofuran (100 ml) was stirred under nitrogen atmosphere at −25° C. for 30 minutes. To the reaction solution was added a saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate, dried over anhydrous sodium sulfate, filtered and concentrated. The resulting residue was subjected to silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain 0.40 g of the desired product.
