Procedure

Tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (66 mg, 0.03 eq.), 3-iodobenzotrifluoride (336 μL, 1.1 eq.), triethylamine (889 μL, 3.0 eq.), and copper (I) iodide (24.3 mg, 0.06 eq.) were added sequentially to a solution of 2-ethyl-1-(2-propynyl)-1H-imidazo[4,5-c]quinoline (500 mg, 2.13 mmol, 1.0 eq.) in DMF (10.6 mL). The reaction mixture was stirred at ambient temperature for 1 hour and then concentrated under reduced pressure. The residue was purified by column chromatography (silica gel eluting with 2/98 methanol/chloroform) to provide 0.73 g of 2-ethyl-1-[3-(3-trifluoromethylphenyl)-2-propynyl]-1H-imidazo[4,5-c]quinoline as a light tan solid.
