Reaction Steps

To a solution of 4-methoxy-2-nitrobenzoic acid (10.0 g, 50.7 mmol) in DMF (200 mL) at 0° C. was added DBU (15.2 mL, 101 mmol) followed by iodomethane (9.47 mL, 152 mmol). The reaction mixture was allowed to stir at 0° C. for 15 min then at rt overnight. The mixture was poured into water and extracted with EtOAc. The organic solutions were combined, washed with brine and dried over MgSO4. The residue was purified by column chromatography to give methyl 4-methoxy-2-nitrobenzoate (50.7 mmol, 85%) as a yellow solid. LCMS (FA): m/z=212.1 (M+H).
