Reaction Steps

To a stirred solution of 2-(4-bromophenyl)-1-[3-fluoro-4-(methylsulfonyl)phenyl]-4-trifluoromethyl-1H-imidazole (0.361 g, 0.78 mmol) in 1,4-dioxane (12 mL) was added 4-(tributylstannyl)thiazole (0.35 g, 0.94 mmol), lithiun chloride (0.083 g, 1.95 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.090 g, 0.078 mmol) at room temperature under nitrogen. The mixture was heated at reflux temperature for 3 hours. After cooling, volatiles were removed by evaporation. The residue was redissolved in ethyl acetate (30 mL) and the whole washed with water and brine. After dried over MgSO4 and concentration in vacuo. The crude mixture was purified by flash chromatography eluting with hexane/ethyl acetate (3/1). The resulting solid was recrystallized from ethyl acetate-hexane to give the title compound (0.319 g, 87.6% yield).
