Reaction Steps
Tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (95 mg, 0.03 eq.), 4-iodonitrobenzene (0.84 g, 1.1 eq.), triethylamine (0.92 g, 3 eq.), and copper (I) iodide (35 mg, 0.06, eq.) were added sequentially to a solution of 2-ethyl-1-(2-propynyl)-1H-imidazo[4,5-c]quinolin-4-amine (0.72 g, 3.0 mmol, 1.0 eq.) in DMF. The reaction mixture was stirred at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure and the residue was partitioned between dichloromethane (30 mL) and water (50 mL). The organic layer was separated, washed twice with water, and then concentrated under reduced pressure to a solid. This material was purified by column chromatography (silica gel eluting with 3/97 methanol/dichloromethane) to provide 0.4 g of 2-ethyl-1-[3-(4-nitrophenyl)-2-propynyl]-1H-imidazo[4,5-c]quinoline.
