Methanol → Methyl 4-bromo-2-methylbenzoate

Participants

Reaction Steps

4-Bromo-2-methylbenzoic acid (75.0 g) was dissolved in methanol (500 ml) and concentrated sulfuric acid (10 ml) was added. The mixture was heated at reflux for 20 hrs. The reaction mixture was cooled to room temperature, and concentrated under reduced pressure. Water (150 ml) was added to the obtained residue, and the mixture was extracted with ethyl acetate (150 ml). The organic layer was washed successively with water, saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over sodium sulfate, and concentrated under reduced pressure to give the title compound (78.0 g).
