Reaktionsschritte

3,4-Dimethylbenzoic acid (64.4 g, 429 mmol) was dissolved in methanol (600 ml), and sulfuric acid (9 ml) was added, which was followed by reflux under heating for 5 hours. The reaction mixture was concentrated to 160 ml and water was added. The mixture was extracted with ethyl acetate, and the organic extract was washed successively with water, 10% aqueous sodium hydroxide solution and saturated brine, dried over anhydrous sodium sulfate, filtered and concentrated to give 68.0 g of methyl 3,4-dimethylbenzoate (yield 97%).
