Benzyl 4-(3-oxo-4-morpholinyl)piperidin-1-carboxylate (3.8 g) obtained in Example 7b) was dissolved in ethanol (50 mL), 10% palladium on carbon (containing 50% water; 0.38 g) was added thereto, and the mixture was stirred at room temperature for 15 hours under a hydrogen atmosphere. The reaction mixture was filtered and the solvent was distilled off under reduced pressure to obtain the title compound (2.2 g, quantitative) as a light yellow oil.
