Reaction Steps

To a solution mixture of the obtained tert-butyl 2-(7-(benzyloxy)-2,3-dihydrobenzo[1,4]dioxine-6-carboxamido)-4-phenylbenzoate (0.49 g) in methanol (4 mL) and ethyl acetate (4 mL), 10% palladium-carbon (0.24 g) was added, followed by stirring under a hydrogen atmosphere at room temperature for 3 hours. The insoluble substance was removed by filtration, and the solvent was evaporated under reduced pressure. Diisopropyl ether was added to the obtained residue, and the solid substance was collected by filtration to obtain 0.37 g of tert-butyl 2-(7-hydroxy-2,3-dihydrobenzo[1,4]dioxine-6-carboxamido)-4-phenylbenzoate as a white solid.
