Reaction Steps
A solution of methyl 4-nitro-2-(trifluoromethoxy)phenyl carbonate (70 mg, 0.25 mmol) in ethyl acetate (10 mL) was stirred in presence of 10% Pd (27 mg) under H2 atmosphere for 4 h. The reaction was filtered through a pad of Celite and concentrated in vacuo to provide 4-amino-2-(trifluoromethoxy)phenyl methyl carbonate (45 mg, 72% yield). 1H NMR (400.0 MHz, CDCl3) δ 7.02 (d, J=8.7 Hz, 1H), 6.62-6.60 (m, 1H), 6.56 (dd, J=2.7, 8.7 Hz, 1H), 3.90 (s, 3H), 3.78 (br s, 2H).
