실험 절차

To a solution of tert-butyl (2-nitro-4-(thiophen-2-yl)phenyl)carbamate (2 g, 6.2 mmol, 1.0 eq.) in ethanol (20 mL) and methanol (20 mL) was added 10% Pd/C (0.66 g, 0.1 eq.). The reaction mixture was stirred 12 h under a hydrogen atmosphere. The reaction was filtered and the filtrate was concentrated under reduced pressure to give tert-butyl (2-amino-4-(thiophen-2-yl)phenyl)carbamate (1.25 g, 69% yield) as an off-white solid.
