Versuchsvorschrift

4-Amino-2-ethoxymethyl-1-(2-hydroxy-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-ol (100 mg, 0.3 mmol), cesium carbonate (488 mg, 1.5 mmol), 4-(chloromethyl)thiazole.HCl (102 mg, 0.6 mmol), tetrabutylammonium bromide (96 mg, 0.3 mmol), triethylamine (0.5 ml), and DMF (10 mL) were combined and stirred at ambient temperature overnight. The reaction was concentrated under reduced pressure and dichloromethane was added to the residue. Undissolved solids were removed by filtration. The filtrate was concentrated under reduced pressure and subsequently purified by flash column chromatography on silica gel, eluting with a gradient of 0-4% methanol in dichloromethane. The clean fractions were combined and concentrated under reduced pressure. The resulting solid was recrystallized from acetonitrile to yield 62 mg of 1-[4-amino-2-ethoxymethyl-7-(thiazol-4-ylmethoxy)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol as a white powder, mp 190.0-191.0° C.
