Procedure
A mixture of (S)-N-{3-[4-(1-oxa-6-aza-spiro[2.5]oct-6-yl)-3-fluorophenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide (0.275 mmol) ethylene glycol (0.330 mmol) and Catalytic amount of BF3.etharate in 10 ml tetrahydrofuran was stirred under reflux for 2 hours. The reaction mixture was evaporated to the dryness under vacuum. The residue obtained was purified on the silica gel column chromatography to provide title compound in 44% yield.
