4-Bromobenzenesulfonamide Chemical Properties,Uses,Production

Uses

4-Bromobenzenesulfonamide was used as reagent in preparation of cobalt(III) complexes of N,R-sulfonyldithiocarbimate anion. It was also used in the synthesis of 2-, 3- and 4-(substituted-phenylethynyl)benzenesulfonamides.

General Description

4-Bromobenzenesulfonamide is a metabolite of ebrotidine, a new H₂-receptor antagonist.

Synthesis

98-58-8

701-34-8

Preparation of 4-bromobenzenesulfonamide: 4-bromobenzenesulfonyl chloride (1.0 g, 3.9 mmol) was dissolved in methanol (5 mL), methanol/ammonia solution (5 mL, excess) was added, and the mixture was mixed in a 25 mL single-neck flask. The reaction mixture was stirred overnight at room temperature under nitrogen protection. On the next day, the reaction solution was concentrated under reduced pressure to give p-bromobenzenesulfonamide (1.13 g, 100% yield) as a white solid. The product was confirmed by ion spray mass spectrometry (m/z 235.9 [M*]) and could be used for subsequent reactions without further purification.
