Reaction Steps

To 4-methoxy-2-methyl-5-nitrobenzoic acid (1.06 g, 5 mmol) in methanol (10 mL) was added thionyl chloride (0.36 mL, 5 mmol) dropwise. The mixture was heated to reflux for 5 h and then allowed to cool. The solvent was removed in vacuo and the residue was partitioned between DCM (20 mL) and saturated aqueous NaHCO3 (20 mL). The organic phase was passed through a hydrophobic frit and the solvent was removed in vacuo to give methyl 4-methoxy-2-methyl-5-nitrobenzoate (998 mg, 89%) as an off-white solid. LCMS (10 cm_ESCI_Bicarb_MeCN): [M+H]+=226 at 3.25 min. 1H NMR (400 MHz, CDCl3): δ 8.56 (s, 1H), 6.91 (s, 1H), 4.01 (s, 3H), 3.90 (s, 3H), 2.71 (s, 3H).
