Procedure

To (3,5-Bis-difluoromethoxy-phenyl)-(5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanol (530, 70.0 mg, 0.16 mmol) in tetrahydrofuran (6.0 mL) was added Dess-Martin periodinane (75.0 mg, 0.18 mmol). The reaction was stirred at room temperature for 10 minutes. The reaction mixture was concentrated with silica gel and purified with silica gel column chromatography eluting with 30% ethyl acetate in hexane to give the compound as a white solid (P-1519, 65.0 mg, 93%.). MS (ESI) [M−H+]−=431.0. 433.0.
