Reaction Steps

To a solution of 2-methyl-2-butanamine (11.4 mL, 97.8 mmol) in dichloromethane (100 mL) was added, dropwise over a 10 min period, a solution of 2-bromobenzenesulfonyl chloride (10.0 g, 39.1 mmol) in dichloromethane (ca. 50 mL). After stirring for 15 h the reaction was concentrated in vacuo. The residue was crystallized from methyl t-butyl ether to provide 10.5 g (87%) of 2-bromo-N-(1,1-dimethylpropyl)benzenesulfonamide in two crops: LCMS (neg. ion spectrum) m/z 304/306.
