To a solution mixture of the obtained methyl 2-(2-(benzyloxy)-5-(1-(2-hydroxyethyl)piperidin-4-yl)benzamido)-4-phenylbenzoate (0.085 g) in ethyl acetate (1.0 mL) and methanol (1.0 mL), 10% palladium-carbon (0.040 g) was added, followed by stirring under a hydrogen atmosphere at room temperature for 2 hours. To the reaction mixture, 10% palladium-carbon (0.040 g) was added, followed by stirring under a hydrogen atmosphere at room temperature for 4 hours. The insoluble substance was removed from the reaction mixture by filtration, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 100-92% chloroform/methanol] to obtain 0.035 g of methyl 2-(2-hydroxy-5-(1-(2-hydroxyethyl)piperidin-4-yl)benzamido)-4-phenylbenzoate as a white solid.
