Sulfuric Acid → Methyl 4-bromo-3-methylbenzoate

Participants

Reaction Steps

4-Bromo-3-methylbenzoic acid (10 g) was suspended in methanol (50 ml) containing conc. sulphuric acid (2 ml). The mixture was heated to reflux for 18 h. On addition of 8% NaHCO3 (100 ml) to the cooled reaction, a flocculent solid was filtered off and dried in vacuo at 40°-45° to give the title compound as a liquid which recrystallised on cooling (10.25 g) m.p. 39.5°-40.5°.
