YieldReaction ConditionsOperation in experiment
In a 2 L, one necked, round-bottomed flask were charged 130 g (0.49 mol) of a mixture of <strong>[881415-27-6]2-bromo-3-fluoro-6-nitro-benzoic acid</strong> and 2-bromo-3-fluoro-5-nitro benzoic acid and 900 mL of methanol. To the mixture, 84 g (0.52 mol) of cesium carbonate was added and the resulting suspension was stirred for 30 minutes. The reaction mixture was concentrated under reduced pressure to remove the solvent. To the mixture 900 mL of DMF followed by iodomethane (33.7 mL, 0.54 mmol) was added and the mixture was stirred for 17 hours. The reaction mixture was poured into the crushed ice and extracted twice with ethyl acetate. The combined organic layers were washed with water, 1M HCl and brine, dried over sodium sulfate and evaporated under reduced pressure to give a mixture of <strong>[881415-27-6]2-bromo-3-fluoro-6-nitrobenzoic acid</strong> methyl ester and 2-bromo-3-fluoro-5-nitrobenzoic acid methyl ester (2:1) a brown oil in quantitative yield. 1H-NMR (400 MHz, CDCl3, delta, ppm) <strong>[881415-27-6]2-bromo-3-fluoro-6-nitrobenzoic acid</strong> methyl ester: 4.04 (s, 3H), 7.34 (dd, 1H), 8.24 (dd, 1H), 2-bromo-3-fluoro-5-nitrobenzoic acid methyl ester:
