Procedure

Trifluoroacetic anhydride (2.24 ml, 15.8 mmol) was added dropwise at room temperature to a solution of N-[[(5S)-3-[3,5-difluoro-4-(tetrahydro-1-oxido-2H-thiopyran-4-yl)phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (2.04 g, 5.28 mmol and N-methylmorpholine (2.90 ml, 26.4 mmol) in dichloromethane (50 ml). The reaction mixture was stirred overnight at room temperature and then evaporated to dryness. The resulting crude N-({(5S)-3-[4-(3,4-dihydro-2H-thiopyran-4-yl)-3,5-difluorophenyl]-2-oxo-1,3-oxazolidin-5-yl}methyl)acetamide (1.95 g) was dissolved in tetrahydrofuran (100 ml) and peracetic acid (5.6 ml of a 32% solution in acetic acid, 26.4 mmol) added dropwise at 0° C. The reaction mixture was allowed to warm to room temperature, stirred overnight, and then evaporated to dryness. The residue was purified by flash column chromatography (ethyl acetate) to give white solid (1.80 g, 85%)
