Procedure
To a stirring solution of 4-(ethylthio)benzoic acid (1 g, 5.5 mmol) in methanol (30 mL) at 0° C. under argon was added a solution of potassium peroxymonosulfate (6.8 g, 11 mmol) in water (30 mL). The resulted suspension was stirred at room temperature for 15 h. Methanol was evaporated under vacuum, the reaction mixture was diluted with water (30 mL), and the product was extracted with EtOAc (2×30 mL). The combined organic phase was washed with brine, dried (MgSO4), filtered and concentrated under reduced pressure to obtain 910 mg of title compound as a white solid. HPLC/MS: retention time=1.695 min, [M+H]+=215.
