実験手順
To a solution of tert-butyl (3-nitrophenyl)carbamate (10.75 g, 45.12 mmol) in MeOH (150 mL) was added catalyst 10% Pd/C (0.48 g). The reaction mixture was stirred at rt under H2 overnight, and filtered. The filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=4:1) to give the title compound as a pale yellow solid (7.59 g, 81%).
