4-Bromobenzenesulfonamide Use and Manufacturing
Preparation of 4-bromobenzenesulfonamide Preparation of 4-Bromobenzenesulfonamide Example 16; 239 240 241Part A:Ammonia gas was bubbled into a solution of compound 239 (1.00 g, 3.91 mmol) in 1 , 4-dioxane (20 ml_) at OConcentrated ammonia solution (12 mL) was added dropwise over 15 minutes to a stirred solution of 4-bromobenzenesulfonyl chloride (6.0 g, 23.6 mmol) in MeOH (60 mL) at room temperature. The mixture was stirred for one hour then concentrated under reduced pressure to leave a solid which was taken up in cold water (50 mL). The solid was collected by filtration, washed with water (2 x 10 mL) and dried to give the title compound (5.0 g, 85percent) as a white solid.
