To a solution of 4.0 g (16 mmol) 2-bromobenzenesulfonyl chloride in 75 mL methylene chloride at 0° C. was added 3.7 mL (35 mmol) tert-butylamine. The mixture was allowed to warm to RT and stir for 1 hour. The mixture was poured into aqueous 5% HCl and extracted three times with ether. The combined organic material was dried over MgSO4, was stripped of solvent in vacuo, then was recrystallized from hexane/acetone to give 3.19 g (70% yield) of the title compound. Rf 0.17 in 10% EtOAc/hexane, visualized by UV;
