Procedure

To (3-dibenzylamino-2,6-difluoro-phenyl)-(5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanol (54, 0.90 g, 1.7 mmol) in methylene chloride (20 mL) under an atmosphere of nitrogen was added Dess-Martin periodane (0.97 g, 2.3 mmol). The reaction was stirred at room temperature for 15 minutes. The reaction was poured into a solution of sodium bicarbonate and sodium thiosulfate and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 5% methanol in methylene chloride to provide the compound (55, 0.70 g, 78%). MS (ESI) [M+H+]+=531.2.
