Methyl cis(±)-2-(acetylamino)-5-(4-{[(benzyloxy)carbonyl]amino}-3-methoxypiperidin-1-yl)benzoate obtained in Example (185c) was dissolved in ethanol (25 mL). A 10% palladium-carbon catalyst (180 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 210 mg of the title compound. The resulting compound was used for the next reaction without purification.
