Reaction Steps
To 2-({5-[2-(4-tert-Butyl-phenyl)-2-(4-iodo-phenylcarbamoyl)-ethyl]-thiophene-2-carbonyl}-amino)-ethanesulfonic acid (100 mg, 0.16 mmol) in 2 ml 1,2-dimethoxyethane, 1 ml ethanol, and 0.5 ml water was added benzofuran-2-boronic acid (76 mg, 0.47 mmol), sodium carbonate (83 mg, 0.78 mmol), and dichlorobis(tri-o-tolylphosphine)palladium(II) (12 mg, 0.016 mmol). The resulting mixture was heated to 125° C. in microwave for 6 minutes. Chromatography of the reaction mixture (20% to 80% acetonitrile in water) obtained 2-({5-[2-(4-Benzofuran-2-yl-phenylcarbamoyl)-2-(4-tert-butyl-phenyl)-ethyl]-thiophene-2-carbonyl}-amino)-ethanesulfonic acid as a white solid (12 mg, 12%).
