Participants

Reaction Steps

To a solution of 42 mg (0.08 mmol) of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(5-chloropyridin-2-yl)-3-methyl-1-((S)-1-morpholinobutan-2-yl)piperidin-2-one (Example 121, Step N) in THF (6 mL) and water (2 mL) added a catalytic amount of osmium tetroxide. After 3 min, 87 mg (0.41 mmol) of sodium periodate was added. The resulting white slurry was stirred at room temperature for 4.25 h, and then filtered through a fritted funnel. The filtrate was partially concentrated under reduced pressure, and then was diluted with a mixture of water and saturated aqueous sodium chloride and extracted with ethyl acetate (2×). The combined organic layers were washed with saturated aqueous sodium thiosulfate and then saturated aqueous sodium chloride. The organic layer was dried over Na2SO4, filtered and the filtrate was concentrated. Purification of the residue by reversed phase prep. HPLC (Sunfire™ Prep C18 OBD 10 μm column (Waters, Milford, Mass.), gradient elution of 35% MeCN in water to 75% MeCN in water over a 35 min period, where both solvents contain 0.1% TFA provided the title compound as a white solid.
