(5R)-3-(3-Fluoro-4-{4-ethyl-3-oxopiperazin-1-yl}phenyl)-5-hydroxymethyloxazolidin-2-one (830 mg) was dissolved in pyridine (20 ml), and cooled to 0° C. Triethylamine (0.41 ml) and methanesulfonyl chloride (0.21 ml) were added, and stirring continued at ambient temperature for 2 hours. Solvent was evaporated and the residue dissolved in ethyl acetate. The resulting solution was washed with water, dried (MgSO4), and evaporated to give (5R)-3-(3-fluoro-4-{4-ethyl-3-oxopiperazin-1-yl}phenyl)-5-(methanesulfonyloxymethyl)-oxazolidin-2-one (1.0 g) which was used without further purification.
