Procedure

To a mixture of (5R)-(−)-3-[3-fluoro-4-(4-morpholinyl)phenyl]-N-benzyloxy -2-oxo-5-oxazolidinecarboxamide (Step 1, 300 mg, 0.722 mmol) in methanol (28.8 mL) is added 5% palladium-on-carbon (77 mg) under nitrogen. The resulting mixture is degassed and stirred under a hydrogen atmosphere (balloon) for 1 h. The catalyst is then removed by filtration through Celite, rinsing with methanol (60 mL), and the filtrate is concentrated under reduced pressure. Trituration of this residue with (5% methanol methylene chloride)/diethyl ether gives the title compound, mp 141-143° C.; MS (ESI+) for C14H16FN3O5 m/z 326 (M+H)+; [α]25D=−70° (c 0.99, DMSO).
