Water → 3,4-difluoro-N-methylbenzene-1-sulfonamide

Participants

Reaction Steps

Commercially available 3,4-difluorophenylsulfonylchloride (117 μL, 0.87 mmol) was dissolved in dichloromethane (5 mL), and methylamine hydrochloride (49 mg, 0.73 mmol) and triethylamine (203 μL, 1.45 mmol) were added, followed by stirring at room temperature for 2 hours. To the reaction solution, water (15 mL) was added, extraction was carried out twice with dichloromethane (15 mL), and washing was carried out with saturated brine (15 mL), followed by drying over sodium sulfate. The solvent was distilled off under reduced pressure, followed by vacuum drying, to afford the desired compound (44.7 mg, yield 30%) as a colorless oil.
