Versuchsvorschrift

A solution of 2-chloro-5-(hydroxymethyl)benzenesulfonamide (696 mg, 3.14 mmol) in acetone (30 mL) was added to a round bottom flask containing MnO2 (2.73 g, 31.4 mmol). The mixture was stirred for 50 hours until the starting material was consumed, then filtered though a pad of celite. The filtrate was evaporated to afford the product (444 mg, 64%) as a white solid. MS (ES+) m/z 220 [M+H]+.
