Methyl iodide → 5-Bromo-1,2-dimethyl-3-nitrobenzene

Participants

Reaction Conditions

Reaction Steps

To stirred solution of 5-bromo-2-methyl-3-nitrobenzoic acid (287 g, 1103 mmol) in DMF (150 mL), sodium carbonate (468 g, 4415 mmol) and methyl iodide (626.63 g, 4415 mmol) were added. Resulting reaction mass was heated at 60° C. for 8 h. On completion, solid precipitated was filtered, residue washed with diethyl ether (5 times). Combined organic layers were dried, concentrated under reduced pressure giving the desired crude compound (302 g, 99%) which was used without further purification.
