Pyridine → N-(3-formylphenyl)methanesulfonamide

참여 물질

반응 단계

1.3 g (10.73 mmol) of 3-aminobenzenecarbaldehyde were initially charged in 30 ml of dichloromethane. 849 mg (10.73 mmol) of pyridine and 1.3 g (10.73 mmol) of methanesulfonyl chloride were added, and the mixture was then stirred at RT overnight. Ethyl acetate was added, and the reaction solution was washed in each case once with 1 N hydrochloric acid, water and saturated aqueous sodium bicarbonate solution. The organic phase was dried over sodium sulfate, filtered and evaporated. The residue was purified by column chromatography on silica gel 60 (mobile phase: dichloromethane/methanol 100/0→50/1).
