Procedure

To a solution of 2′-tert-butylaminosulfonyl-4-amino-[1,1′]-biphenyl (139 mg, 0.46 mmol) in 4 ml anhydrous dichloromethane was added a solution of 2M trimethylaluminum in hexane (0.69 ml, 1.38 mmol). Reaction was stirred at room temperature for 20 minutes to which a solution of crude methyl (2Z)-3-(3-cyanophenyl)-4-methylpent-2-enoate (105 mg, 0.46 mmol) in 2 ml anhydrous dichloromethane was added. Reaction was stirred at room temperature overnight. Reaction was quenched with 5 ml 1N HCl after which an additional 20 ml dichloromethane was added. Organic was washed with 2×20 ml water, dried over magnesium sulfate, filtered and concentrated to give (2Z)-N-[4-(2-{[(tert-butyl)amino]sulfonyl}phenyl)phenyl]-3-(3-cyanophenyl)-4-methylpent-2-enamide (190 mg, 82%) as an off-white foam which was sufficiently pure to be used without further purification. ES-MS (M+H): 501.2.
