Versuchsvorschrift

To a stirred solution of 3-dimethylcarbamoylthio-4-methoxybenzoic acid methyl ester (530 mg, 1.97 mmol) in THF (10 mL), was added MeONa (10 mL, 0.5 M solution in MeOH). The resulting mixture was heated to reflux for 3 h and then cooled to room temperature. The reaction mixture was diluted with 1N HCl aqueous solution (100 mL), extracted with EtOAc (3×50 mL). The combined organic layer was washed with brine (100 mL), dried over Na2SO4, concentrated in vacuo to afford 3-mercapto-4-methoxybenzoic acid methyl ester (0.42 g). The product was used without further purification.
