Dess Martin Periodinane (392 mg, 0.93 mmol) was added to a solution of (2-[3-(hydroxymethyl)phenyl]-N-{5-[(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)carbonyl]pyridin-3-yl}acetamide (Preparation 193, 265 mg, 0.62 mmol) in dichloromethane (15 mL) and the mixture was stirred at room temperature for 18 hours. Water (10 mL) was added and the aqueous layer extracted with a 95:5 mixture of dichloromethane/methanol (3×10 mL). The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography using silica gel (gradient of dichloromethane to dichloromethane/methanol (10:1 to 9:1) to afford the title compound as a brown solid in 80% yield, 211 mg.
