Methyl cis(±)-4-(4-{[(benzyloxy)carbonyl]amino}-3-methoxypiperidin-1-yl)pyridine-2-carboxylate obtained in Example (160b) (74.8 mg) was dissolved in ethanol (10 mL). A 10% palladium-carbon catalyst (100 mg) was added, and the mixture was stirred in a hydrogen atmosphere overnight. The reaction solution was filtered through celite and then concentrated under reduced pressure, to obtain 21.2 mg of the title compound as a colorless oily substance. The resulting compound was used for the next reaction without purification.
