Procedure

To a reaction flask were added 3.0 g of dihydrochloride of 3-(3-fluoro-4-morpholinylphenyl)-5-[(1-phenylethyl)aminomethyl]-1,3-oxazolidin-2-one (4a), 100 ml of methanol and 1.0 g of 10% Pd(OH)2/C. Gas inside the reaction flask was evacuated and argon was then introduced to the reaction flask. The reaction mixture was allowed to react for 48 hours at room temperature with stirring. After the reaction was completed, the reaction mixture was filtered, and subsequently put under reduced pressure for solvent removal to give a dihydrochloride of 3-(3-fluoro-4-morpholinylphenyl-5-aminomethyl-1,3-oxazolidin-2-one (5a) as a white solid and at a yield of 95%.
