Reaction Steps

To a stirred solution of 2-methyl 5-[4-(methylsulfonyl)phenyl]-1-(4-bromophenyl)-1H-pyrrole (0.2 g, 0.51 mmol) in DME (6 ML) was added thiophene-3-boronic acid (0.079 g, 0.61 mmol), bis(triphenylphosphine)palladium(II)chloride (0.04 g, 0.06 mmol) and saturated NaHCO3 solution (2 mL) at room temperature under nitrogen. The mixture was heated at reflux temperature for 6 hours, and cooled down to room temperature. The reaction mixture was filtered through celite, the filtrate was poured into water and the whole was extracted with ethyl acetate (10 mL×3). The organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash chromatography eluting with hexane/ethyl acetate (4/1). The resulting solid was recrystallized from ethyl acetate/hexane to give the title compound (0.15 g, 75.0% yield).
