To a solution of N-(4-acetyl-3-hydroxyphenyl)acetamide (4.0 g, 20.7 mmol) in methanol (50 mL)/acetic acid (50 mL) was added 10% palladium-carbon powder (2.0 g), and the mixture was stirred at room temperature for 6 hr under a hydrogen atmosphere of 2.8 pressure. 10% Palladium-carbon powder was filtered off by celite filtration, the filtrate was concentrated under reduced pressure, and the obtained residue was washed with diisopropyl ether/hexane (1:1) to give the title compound (3.07 g, 83%) as a colorless powder.
