A mixture of (S)-N-[[3-[3-fluoro-4-(1-piperazinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (0.200 g, 0.595 mmol), 3-chloro-1-propanol (299 μL, 3.57 mmol) and potassium carbonate (0.493 g, 3.57 mmol) in acetonitrile (12 mL) was heated to reflux for 7 h. The reaction mixture was cooled to ambient temperature and concentrated in vacuo. The crude material was dissolved in 10% methanol/chloroform and absorbed onto silica gel (2 g). Chromatography of this material over silica gel (10 g), eluting with 1%, 3%, and then 6% methanol/chloroform, afforded, after concentration of appropriate fractions, 0.096 g (41%) of the title compound as a white solid with mp 154°-155.5° C.
