실험 절차
A round bottom flask was charged with a magnetic stir bar, 2-butyl-1-(4-chlorobutyl)-1H-imidazo[4,5-c]quinolin-4-amine (1.5 g, 4.53 mmol), sodium thiomethoxide (0.48 g, 6.80 mmol), and anhydrous dimethyl formamide (18 mL) under a nitrogen atmosphere. The reaction mixture was heated to 60° C. to give a homogeneous solution that was maintained at 60° C. for 16 hours at which time the starting material was completely consumed. The solution was cooled and then partitioned between chloroform and water. The layers were separated and the organic layer was washed with saturated aqueous sodium bicarbonate. The combined aqueous layers were extracted with chloroform (1×). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, filtered and then concentrated under reduced pressure to afford a dark brown oil. The material was purified by chromatography over silica gel (90/10 dichloromethane/methanol) to provide a light yellow solid. The solid was recrystallized from dimethyl formamide and water to give 2-butyl-1-[4-(methylthio)butyl]-1H-imidazo[4,5-c]quinolin-4-amine (0.83 g, 2.42 mmol) as light yellow needles, m.p. 127–130° C.
