実験手順

1-[3-(Dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.57 g, 3.0 mmol) was added dropwise to a chilled (0° C.) solution of 2-phenyl-4-quinolinecarboxylic acid (0.5 g, 3.7 mmol), 1-hydroxybenzotriazole (0.5 g, 3.7 mmol), pyridine (2.2 ml), and dichloromethane (20 ml). The reaction was maintained for 15 min followed by the dropwise addition of 1-(4-aminobutyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-4-amine (0.8 g, 2.55 mmol) in dichloromethane (100 ml). The reaction was maintained at room temperature overnight. The solvent was removed in vacuo and the residue was purified by flash column chromatography (silica gel, 9:1 dichloromethane\methanol). The fractions containing product were combined, washed with saturated aqueous sodium bicarbonate, dried (MgSO4), filtered, and concentrated to provide 0.62 g of N4-[4-(4-amino-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl)butyl]-2-phenyl-4-quinolinecarboxamide as a yellow crystalline solid, m.p. 118° C. (decomposition). 1H NMR (300 MHz, DMSO-d6) δ 8.88 (t, J=5.7 Hz, 1H), 8.24-8.21 (m, 2H), 8.13-8.01(m, 4H), 7.83-7.78 (m, 1H), 7.62-7.48 (m, 5H), 7.36 (m, 1H), 7.20 (dt, J=7.6, 1.2 Hz, 1H), 6.54 (broad s, 2H), 4.62 (t, J=7.2 Hz, 2H), 3.83 (t, J=6.7 Hz, 2H), 3.45 (m, 2H), 3.29-3.20 (m, 5H), 1.96 (m, 2H), 1.79 (m, 2H); MS (EI) m/e 544.2589 (544.2587 calcd for C33H32N6O2).
