実験手順

A mixture of 4-phenylthiobenzoic acid (26.29 g), conc. sulfuric acid (5 ml) and methanol (400 ml) is refluxed with stirring for 10 hours. After the reaction is completed, the reaction mixture is concentrated under reduced pressure, and to the residue is added ethyl acetate (400 ml). The mixture is washed with saturated aqueous sodium chloride solution (200 ml×3), dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give methyl 4-phenylthiobenzoate (27.44 g).
