A mixture of 26.29 g of 4-phenylthiobenzoic acid, 5 ml of concentrates sulfuric acid, and 400 ml of methanol was refluxed for 10 hours while stirring. After reaction, the reaction mixture was concentrated in vacuo, and 400 ml of ethyl acetate was added to the residue, and the mixture was washed with saturated brine (200 ml×3), and dried in anhydrous magnesium sulfate, concentrated in vacuo, and methyl 4phenylthiobenzoate was obtained (27.44 g).
