Procedure

Methanesulfonic acid (5R)-3-[4-(3,6-dihydro-2H-thiopyran-4-yl)-3-fluorophenyl]-2-oxo-oxazolidin-5-ylmethyl ester (8 g, 19.7 mmol) and sodium azide (4 g, 61.5 mmol) were heated in N,N-dimethylformamide (75 ml) at 80° C. for 2 hours. It was cooled to room temperature, diluted with ethyl acetate, washed with potassium phosphate buffer (pH 7) and with water and dried over sodium sulfate. After evaporation of the solvent the title product was obtained as a brown oil (˜7 g, crude).
