실험 절차

To a solution of tert-butyl(4-fluoro-3-nitrophenyl)methylcarbamate (1.0 g, 3.70 mmol) in methanol (4 mL) was added 10% palladium-carbon (150 mg), and the mixture was stirred under a hydrogen atmosphere (1 atm) at room temperature for 18 hr. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate), and the obtained solution was concentrated under reduced pressure to give the title compound (0.88 g, 99%) as a brown oil.
