(5R)-5-(Azidomethyl)-3-(3-fluoro-4-iodophenyl)-1,3-oxazolidin-2-one (Intermediate 5, 5.00 g, 0.014 mol) was suspended in thioacetic acid (10 ml) and the solution was stirred under nitrogen at room temperature for ca. 16 h. The resulting suspension was concentrated under vacuum. The crude product was crystallized from methanol/acetone, then further purified by chromatography on silica gel using dichloromethane to give 3.71 g of the title product as a white solid.
