Versuchsvorschrift

To a solution of tert-butyl(4-methyl-3-nitrophenyl)carbamate (10.1 g, 39.8 mmol) in ethanol (60 mL)/tetrahydrofuran (20 mL) was added 10% palladium-carbon (2.12 g), and the mixture was stirred at room temperature under a hydrogen atmosphere (3 atm) for 22 hr. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (8.82 g, 99%) as a colorless solid.
