실험 절차

To a solution of 197 mg (0.44 mmol) of (5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(5-chloropyridin-2-yl)-1-((S)-1-hydroxybutan-2-yl)-3-methylpiperidin-2-one (Example 121, Step L) in DCM (6 mL) was added 12 μL (0.66 mmol) of water and 280 mg (0.66 mmol) of Dess-Martin periodinane. The resulting light yellow slurry was warmed to room temperature and stirred for 50 min. The reaction was quenched with saturated aqueous sodium thiosulfate, diluted with water, and extracted with DCM (2×). The combined organic layers were washed with saturated aqueous sodium bicarbonate (1×) and saturated aqueous sodium chloride (1×), and then were dried over Na2SO4, filtered and the filtrate was concentrated. Purification of the residue by flash chromatography on silica gel (0 to 7% MeOH/DCM, gradient elution) provided the title compound as a light yellow solid.
