Vorschrift

To a stirred solution of 1-(4-bromophenyl)-4-methyl-2-[4-(methylsulfonyl)phenyl]-1H-pyrrole (0.1 g, 0.26 mmol) in dioxane (5 mL) was added 2-(tributylstannyl)furan (0.118 g, 0.33 mmol), LiCl (0.027 g, 0.64 mmol), tetrakis(triphenylphosphine)palladium(0) (0.03 g, 0.026 mmol) at room temperature under nitrogen. The mixture was heated at reflux temperature for 0.5 hours. After cooling, volatiles were removed by evaporation. The residue was purified by flash chromatography eluting with hexane/ethyl acetate (4/1). The resulting solid was recrystallized from CH2Cl2/hexane to give the title compound (0.026 g, 26.5% yield).
