To a solution of 2-bromo-N-(1,1-dimethylpropyl)benzenesulfonamide (5.00 g, 16.3 mmol) in dimethylformamide (dry, N2-degassed, 20 mL) were added allyltribuylstannane (6.07 mL, 19.6 mmol) and tetrakis(triphenylphosphine)palladium(0) (189 mg, 0.163 mmol). The mixture was heated at 110° C. for 15 h. The reaction was concentrated in vacuo and the residue was chromatographed (silica, 40% dichloromethane/hexanes to dichloromethane gradient) to provide N-(1,1-dimethylpropyl) 2-(2-propenyl)benzenesulfonamide (4.04 g, 92%) as an off-white solid: LCMS (neg. ion spectrum) m/z 266.
