実験手順
Manganese dioxide (85%, 45.0 g, 0.52 mol) was added to a solution of N-[2-(hydroxymethyl)phenyl]methanesulfonamide (13.0 g, 65 mmol) in dichloromethane (200 mL) at ambient temperature under nitrogen. The reaction mixture was stirred for 12 h and then filtered through a pad of Celite. The pad was washed with dichloromethane/methanol (1:1) and the combined organics were concentrated to afford N-(2-Formylphenyl)methanesulfonamide (10.1 g, 78% yield) as a yellow solid.
