실험 절차

To a mixture of methyl 3-hyroxy-4-phenylthiobenzoate (49.11 g), potassium carbonate (27.33 g) and acetone (627 ml) is added dimethyl sulfate (17.85 ml), and the mixture is refluxed with stirring for 6 hours. The reaction mixture is cooled, and the precipitate is separated by filtration and washed with acetone. The filtrate and washings are combined and concentrated under reduced pressure to give methyl 3-methoxy-4-phenylthiobenzoate.
