Procedure

A mixture of 3-methyl-4-phenylthiobenzoic acid (85 g), conc. sulfuric acid (20 ml) and methanol (1.2 liter) is refluxed with stirring for 4 hours. After the reaction is completed, the reaction mixture is concentrated under reduced pressure. To the residue is added ethyl acetate (1.5 liter), and the mixture is washed with saturated aqueous sodium chloride solution (400 ml×3), dried over anhydrous sodium sulfate and concentrated under reduced pressure to give methyl 3-methyl-4-phenylthiobenzoate (80.33 g).
