Reaction Steps

2-Methyl-4,5-dinitrobenzoic acid (1.93 g, 8.5 mmol) was added to KOH (2.38 g, 42.5 mmol) in methanol (50 mL) and the mixture was heated to 70° C. for 1.5 h. The mixture was acidified with 2 M HCl(aq) and the solid was removed by filtration and dried to give 4-methoxy-2-methyl-5-nitrobenzoic acid (1.08 g, 60%) as an off-white solid. LCMS (10 cm_ESCI_Formic_MeCN): [M−H]−=210 at 3.23 min. 1H NMR (400 MHz, d6-DMSO): δ 8.40 (s, 1H), 7.36 (s, 1H), 4.02 (s, 3H), 2.67 (s, 3H).
