Procedure

Add 2,6-lutidine (5.3 mL, 54 mmol) and tert-butyl-dimethylsilyl-trifluoromethylsulfonate (1.62 mL, 7.08 mL) to a solution of 2-(R)-[2-(S)-benzyl-1-(S)-hydroxy-3-(4-(S)-isopropyl-2-oxo-oxazolidin-3-yl)-3-oxopropyl]-4-(R)-fluoropyrrolidine-1-carboxylic acid tert-butyl ester (2.585 g, 5.4 mmol) in dichloromethane (40 mL) at −78° C. Stir 3 h, warm to room temperature, stir 5 min and cool in an ice bath. Add 1 N HCl (100 mL), wash with 1 N HCl (2×100 mL), saturated aqueous sodium bicarbonate, saturated aqueous sodium chloride, dry (magnesium sulfate), concentrate and purify (silica gel chromatography, eluting with hexanes and ethyl acetate) to give the title compound as a white foam (2.779 g, 87%).
