実験手順
A solution of trans-4-[4-(3-{(1S)-1-[2-chloro-6-(difluoromethoxy)-3-fluorophenyl]ethyl}-1H-pyrrolo[2,3-b]pyridin-5-yl)-5-methyl-1H-pyrazol-1-yl]cyclohexanol (70.0 mg, 0.135 mmol), Dess-Martin periodinane (85.82 mg, 0.2023 mmol), NaHCO3 (22.66 mg, 0.2698 mmol) and DCM (4 mL, 70 mmol) was stirred at rt for 5 min. The material was extracted with DCM and sat. NaHCO3, and the organic layer was loaded onto silica gel for column chromatography, eluting with 2-4% MeOH/DCM. The fractions containing the pure product were concentrated in vacuo to afford the title compound as a white solid. MS (ES+): m/z=517.11/519.08 (100/50) [MH+]. HPLC: tR=3.99 min (polar—5 min, ZQ3).
