Reaction Conditions

Reaction Steps

To a stirred solution of 5-bromo-2-methyl-3-nitrobenzoic acid (287 g, 1103 mmol) in DMF (150 mL) was added sodium carbonate (468 g, 4415 mmol) and methyl iodide (626.63 g, 4415 mmol). The resulting reaction mixture was heated at 60° C. for 8 h. On completion, the precipitated solid was collected by filtration, the residue washed with diethyl ether (5 times). The combined organic layers were dried, concentrated under reduced pressure to give methyl 5-bromo-2-methyl-3-nitrobenzoate (302 g, 99%) which was used directly in the next step.
