To a solution of 4-bromobenzenesulfonyl chloride (100.2 g) in THF (400 mL) was added t-butylamine (125 mL). An exothermic reaction results with gentle refluxing of the solvent. After 30 min, the bath was removed and the mixture was allowed to warm to r.t. Isopropyl acetate (400 mL) was added and the mixture was washed twice with water. The aqueous phase was back-extracted with ethyl acetate and the combined organics were dried (sodium sulfate) and concentrated to provide the title compound as a solid (112.9 g).
