Reaction Steps
A solution of methyl 2-methoxy-5-nitrobenzoate (20.0 g, 0.097 mol) in methanol (300 mL) and 10% Pd/C (5.0 g) was stirred under hydrogen atmosphere under 70-80 psi pressure in Parr apparatus for 4-5 h. The reaction mass was filtered and the obtained filtrate was concentrated to afford 15.0 g of desired product. 1H NMR (300 MHz, DMSO de): δ 3.67 (s, 3H), 3.74 (s, 3H), 4.96 (br s, 2H), 6.75 (dd, J=2.4 Hz, 1H), 6.85 (d, J=8.7 Hz, 1H), 6.92 (s, 1H); MS (in/z): 182.25 (M+H)+.
