Versuchsvorschrift
To an ammonium hydroxide (28%, 80 ml) was added a solution of 4-bromo-2-fluorobenzenesulfonyl chloride (10 g) in dichloromethane (80 ml) dropwise for 1 hour at approximately 0° C. The reaction mixture was stirred vigorously for an additional 2 hours at the same temperature. The phases were separated. The aqueous phase was washed with dichloromethane. The combined organic extracts were washed with brine, dried over sodium sulfate and evaporated to give 4-bromo-2-fluorobenzenesulfonamide (8.0 g).
