Reaction Steps

N-Ethyl-2-nitroaniline (0.97 g, 5.8 mmol) was dissolved in EtOAc (60 mL) and placed in a closed vessel. 10% Pd/C (0.4 g, 7 mol %) was added and the mixture was hydrogenated under 50 psi H2 for 2 h. The mixture was filtered through celite and the filtrate was concentrated under reduced pressure to yield the title product (0.79 g, 99%) as a brown liquid, which was used without further purification. 1H-NMR (CDCl3): δ 6.83 (1H, m), 6.64–6.74 (3H, m), 3.29 (3H, br s), 3.15 (2H, q), 1.30 (3H, t); TLC (2:98 MeOH/DCM Rf 0.24).
