In a 250 mL Parr apparatus, 2.1 g (10.6 mmol) of 2-methoxy-4-methoxymethyl-1-nitro-benzene, in 40 mL of ethanol was hydrogenated at 2 atm over 300 mg of 10% Pd on carbon for 2.5 h. The catalyst was removed by filtration through a glass fiber filter and the filtrate was concentrated to give 1.61 g (91%) of product as a light yellow oil. 1H NMR (400 MHz, CDCl3): δ6.80 (s, 1H), 6.74 (d, J=7.8 Hz, 1H), 6.67 (d, J=7.8 Hz), 4.35 (s, 2H), 3.86 (s, 3H), 3.78 (br d, 2H), 3.35 (s, 3H). MS ESI-pos, M+1=168.1
