실험 절차

N{2-[4-Amino-2-(ethoxymethyl)-7-(prop-2-ynyloxy)-1H-imidazo[4,5-c]quinolin-1-yl]-1,1-dimethylethyl}methanesulfonamide (600 mg, 1.34 mmol), 2-iodothiophene (565 mg, 2.69 mmol), triethylamine (0.50 mL, 3.5 mmol), dichlorobis(triphenylphosphine)palladium(II) (19 mg, 0.03 mmol), copper(I) iodide (10 mg, 0.05 mmol), and DMF (10 mL) were combined and heated at 60° C. overnight. After cooling to ambient temperature, the reaction was poured into water (200 mL) and a fine precipitate formed. After the mixture was stirred for 1 hour, the solid was isolated by filtration. The solid was dissolved in dichloromethane and methanol and was passed through a plug of silica gel, which was rinsed with 20% methanol in dichloromethane. The filtrate was concentrated under reduced pressure to yield approximately 900 mg of N-(2-{4-amino-2-(ethoxymethyl)-7-[(3-thien-2-ylprop-2-ynyl)oxy]-1H-imidazo[4,5-c]quinolin-1-yl}-1,1-dimethylethyl)methanesulfonamide as a dark brown semi-solid that was used without further purification in the next step.
