Procedure

To a solution mixture of the obtained tert-butyl 2-(2-(benzyloxy)-5-(piperidin-1-yl)benzamido)-4-(2-methylphenyl)benzoate (0.10 g) in methanol (2.0 mL) and ethyl acetate (2.0 mL), 10% palladium-carbon (0.020 g) was added, followed by stirring under a hydrogen atmosphere at room temperature for 2 hours and 45 minutes. The insoluble substance was removed by filtration, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 99-91% hexane/ethyl acetate] to obtain 0.063 g of tert-butyl 2-(2-hydroxy-5-(piperidin-1-yl)benzamido)-4-(2-methylphenyl)benzoate as a yellow solid.
