Procedure

To propane-2-sulfonic acid {2,4-difluoro-3-[hydroxy-(5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-phenyl}-amide (50, 40.0 mg, 0.087 mmol) in tetrahydrofuran (10 mL) was added Dess-Martin periodane (48.0 mg, 0.11 mmol). The reaction was stirred at room temperature for 5 minutes. The reaction was poured into sodium thiosulfate and potassium carbonate solution and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtrated. The filtrate was concentrated and purified by silica gel column chromatography eluting with 5% methanol in methylene chloride to give the compound (51, 13.4 mg, 33.5%). MS (ESI) [M+H+]+=458.1.
