実験手順

To a solution of benzyl 4-(2-oxoazepan-1-yl)piperidin-1-carboxylate (0.25 g) obtained in Example 9a) in ethanol (10 mL) was added 10% palladium on carbon (containing 50% water; 0.03 g), 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 (0.15 g, quantitative) as a brown oil.
