Reaction Steps

Treat a solution of (R)-4-Benzyl-3-[(S)-2-(6-chloro-2,3-difluoro-4-trifluoromethyl-benzyl)-pent-4-enoyl]-oxazolidin-2-one (Preparation 45) (0.72 g, 1.5 mmol) in THF (9 mL) and water (3 mL) with 2.5% OsO4 in tBuOH (1.5 g, 0.15 mmol). Then, add sodium periodate (0.96 g, 4.5 mmol) to the solution and stir the reaction for 4 hr at room temperature. Quench the reaction with water and extract with EtOAc. Wash the organic with 1N sodium thiosulfate and brine. Separate the organic, dry over MgSO4, filter, and remove the solvent. Purify the crude by silica gel column chromatography using Hexanes:EtOAc to elute the pure product. Remove the solvent to afford 0.60 g (82%) of desired product. MS (m/e): 490 (M+1).
