Methanol → Methyl 3-bromo-4-methylbenzoate

Participants

Reaction Steps

A solution of 3-bromo-4-methylbenzoic acid (20 g, 93.00 mmol, 1.00 equiv) and sulfuric acid (20 mL) in methanol (100 mL) was stiffed overnight at 80° C. The mixture was then concentrated under reduced pressure and the residue was diluted with 500 mL of ethyl acetate. The resulting mixture was washed with 3×200 mL of water, 1×200 mL of sodium bicarbonate (aq), followed by 1×200 mL of brine. The organic phase was dried over anhydrous sodium sulfate, concentrated under reduced pressure, and dried to yield 20 g (94%) of the title compound as a dark red oil.
