To a stirred suspension of 1-(4-bromophenyl)-2-[3-fluoro-4-(methylsulfonyl)phenyl]-5-methyl-1H-pyrrole (0.41 g, 1 mmol), 2-furanboronic acid (0.14 g, 1.26 mmol), NaHCO3 (0.19 g, 2.3 mmol) in DME-water (6 mL-2 mL) was added dichlorobis(triphenylphosphine) palladium (80 mg, 0.115 mmol) at room temperature under nitrogen. The mixture was heated at reflux temperature for 6 hours. After cooling, volatiles were removed by evaporation. The residue was purified by flash chromatography on silica gel eluting with ethyl acetate/hexane (1/2) to give the title compound (0.24 g, 61% yield).
