A mixture of 1-(2-chloroethoxy)-2-methyl-3-nitrobenzene (10.7 g, 50 mmol) in ethanol (200 mL) containing 500 mg of 5% palladium on carbon was hydrogenated at 50 psi for 4 h. The catalyst was filter through Solka Floc and the solvent removed under vacuum to afford 9.1 g (98.8%) a yellow oil: 1H NMR (CDCl3) δ 2.76 (3H, s), 3.92 (2H, t, J=5.9 Hz), 4.40 (2H, t, J=5.9 Hz), 6.70 (1H, d, J=), 7.46 (1H, app t, J=), 8.04 (1H, d, J=), 8.24 (1H, s).
