Procedure

2-((R)-1-(4-hydroxycyclohexyl)ethylamino)-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (442 mg, 0.7561 mmol) was dissolved in dichloromethane (20 mL) and cooled down to 0° C. Dess-Martin periodinane (384.8 mg, 0.9073 mmol) was added and the reaction was allowed to warm up to room temperature. The mixture was stirred for 18 hours. The reaction mixture was partitioned between dichloromethane and a 1:1 saturated solution of sodium hydrosulfite and sodium hydrogen carbonate. The aqueous phase was further extracted with dichloromethane. The combined organic phases were dried over magnesium sulfate, filtered and concentrated to dryness. The residue was purified on silica gel by flash column chromatography (ISCO Companion|, 40 g column, 0-20% EtOAc/DCM) to afford the title compound as a white solid (411 mg, 93% yield).
