Reaction Steps
A mixture of 4,5-dinitro-2-ethoxy-benzoic acid methyl ester (320 mg) and 10% Pd/C (40 mg) in MeOH (8 mL) was stirred under an atmosphere of hydrogen gas for 4 h at r.t., filtered through a plug of Celite and reduced in vacuo to give the title compound (234 mg) as a black gum. 1H NMR (300 MHz, MeOD) δ 7.30 (s, 1H), 6.40 (s, 1H), 4.00 (q, 2H), 3.80 (s, 3H), 1.35 (t, 3H).
