To a solution of tert-butyl {4-methyl-3-[(6-nitropyridin-3-yl)oxy]phenyl}carbamate (1.85 g, 5.35 mmol) in methanol (10 mL) was added palladium carbon (50% water-containing product, 100 mg), and the mixture was stirred under a hydrogen atmosphere at room temperature for 3 hr. The reaction mixture was filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was dried to give the title compound (1.69 g, 99%) as a colorless oil.
