Versuchsvorschrift

Under a nitrogen atmosphere, a mixture of 1-[2-(2-propynyloxy)ethyl]-1H-imidazo[4,5-c]quinolin-4-amine (10 g, 37.6 mmol), anhydrous N,N-dimethylformamide (150 mL) and potassium carbonate (6.23 g, 45.1 mmol) was heated to 70° C. lodobenzene (4.43 mL, 39.5 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.53 g, 0.75 mol), and copper(I) iodide (0.29 g, 1.50 mmol) were added and the mixture was allowed to stir for 0.5 hour. The temperature was raised to about 85° C. After 1.5 hours analysis by HPLC (reverse phase, acetonitrile/water with 0.1% trifluoroacetic acid) indicated that the reaction was complete. The mixture was allowed to cool to ambient temperature and then it was filtered. The filtrate was concentrated under reduced pressure. The residue was purified twice by flash chromatography (95/5 dichloromethane/methanol) to provide 2.7 g of 1-{2-[(3-phenyl-2-propynyl)oxy]ethyl}-1H-imidazo[4,5-c]quinolin-4-amine as a white solid, m.p. 196-197° C.
