The same operation as in Example (90d) was performed using ethyl cis(±)-3-(4-{benzyl[(benzyloxy)carbonyl]amino}-3-methoxypiperidin-1-yl)-5-methylbenzoate obtained in Example (259f) (126 mg, 0.24 mmol), a 10% palladium-carbon catalyst (63 mg), ammonium formate (155 mg, 2.4 mmol) and ethanol (5 mL), to obtain the title compound. The resulting compound was used for the next reaction without purification.
