Reaction Conditions

Reaction Steps

To stirred solution of 5-bromo-2-methyl-3-nitrobenzoic acid, prepared analogously to above, (287 g, 1103 mmol) in DMF (150 mL), sodium carbonate (468 g, 4415 mmol) and methyl iodide (626.6 g, 4415 mmol) were added. Resulting mixture was heated at 60° C. for 8 h. On completion, solid was remove by filtration, and 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-nitrobenzene (302 g, 99%).
