Versuchsvorschrift

To a solution of 3-methoxythioanisole (3.084 g, 20 mmol) in 300 mL acetone was added a solution of oxone (30.74 g, 50 mmol) in 125 mL water, resulting in the formation of a white precipitate. Stirring continued overnight, and the solid was filtered off and washed with acetone. Filtrate was concentrated to remove acetone. Aqueous layer was extracted with EtOAc (2×200 mL) and dried over Na2SO4. The solvent was removed to give 1-methanesulfonyl-3-methoxy benzene (3.68 g, 98%) as oil.
