実験手順

Under a nitrogen atmosphere a solution of 1-(8-aminooctyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-4-amine (1.0 g, 2.7 mmol) in dichloromethane (50 mL) was cooled to 0° C. Triethylamine (415 μL, 2.98 mmol) was added followed by benzenesulfonyl chloride (345 μL, 2.71 mmol). The reaction mixture was allowed to warm slowly to ambient temperature and then it was maintained overnight. The reaction mixture was washed with water, dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified by column chromatography (50 g of silica gel eluting with 7.5% methanol in dichloromethane). The purified material was recrystallized from propyl acetate, triturated with hexanes, and then dried in a vacuum oven to provide 590 mg of N-{8-[4-amino-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]octyl}benzenesulfonamide as a yellow powder, m.p. 146-149° C.
