Procedure

To propane-1-sulfonic acid 3-[(5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)hydroxy-methyl]-4-fluoro-phenyl-amide (673, 55.0 mg, 0.12 mmol) in tetrahydrofuran (8.0 mL) was added Dess-Martin periodinane (70.0 mg, 0.17 mmol). The reaction was stirred at room temperature for 5 minutes. The reaction was concentrated with silica gel and purified with silica gel column chromatography eluting with 25% ethyl acetate in hexane to give an off-white solid (P-1403, 26.2 mg, 47%). MS (ESI) [M+H+]+=437.9, 439.9.
