Procedure

To 2-(4-tert-Butyl-phenyl)-N-(4-iodo-phenyl)-3-(4-nitro-phenyl)-propionamide (1056 mg, 2 mmol) in 8 ml 1,2-dimethoxyethane, 4 ml ethanol, and 2 ml water was added benzo[b]furan-2-boronic acid (972 mg, 6 mmol), bis(tri-o-tolylphosphine)palladium(II) dichloride (158 mg, 0.2 mmol), and sodium carbonate (1060 mg, 10 mmol). The reaction mixture was stirred at 125° C. for 6 min, filtered, and concentrated. Chromatography of the residue (20% ethyl acetate in hexane) afforded N-(4-Benzofuran-2-yl-phenyl)-2-(4-tert-butyl-phenyl)-3-(4-nitro-phenyl)-propionamide as a yellow foam (830 mg, 80%).
