실험 절차
A solution of 4-(chloromethyl)benzoyl chloride (1.06 g, 5.6 mmol) in dichloromethane was added to a suspension of 1-(4-aminobutyl)-1H-imidazo[4,5-c]quinolin-4-amine (1.0 g, 3.9 mmol) in pyridine (250 mL). After 1 hour HPLC analysis indicated that the reaction was complete. The reaction mixture was concentrated under vacuum. The residue was combined with saturated aqueous sodium bicarbonate. A solid was isolated by filtration then dissolved in chloroform containing a small amount of methanol. The solution was washed with saturated aqueous sodium bicarbonate. The organic layer was concentrated under vacuum. The resulting residue was purified by column chromatography (silica gel eluting with 10% methanol in dichloromethane) to provide N1-[4-(4-amino-1H-imidazo[4,5-c]quinolin-1-yl)butyl]-4-(chloromethyl)benzamide as a solid, m.p. 240-300 (dec.). 1H NMR (500 MHz, DMSO-d6) δ8.49 (t, J=6.0 Hz, 1H), 8.21 (s, 1H), 8.03 (d, J=8.0 Hz, 1H), 7.76 (d, J=8.0 Hz, 2H), 7.61 (d, J=8.0 Hz, 1H), 7.46 (d, J=8.0 Hz, 2H), 7.42 (t, J=8.0 Hz, 1H), 7.20 (t, J=8.0 Hz, 1H), 6.80 (broad s, 2H), 4.78 (s, 2H), 4.62 (t, J=7.0 Hz, 2H), 3.28 (q, J=6.0 Hz, 2H), 1.89 (quintet, J=7.0 Hz, 2H), 1.56 (quintet, J=7.0 Hz, 2H); MS (CI) m/e 408 (M+H).
