실험 절차

1-(4-Aminobutyl)-2-butyl-1H-imidazo[4,5-c]quinolin-4-amine (0.5 g, 1.6 mmol) was combined with pyridine (50 mL) and heated to 50° C. Benzoyl chloride (0.22 g, 1.6 mmol) was added via a pipette. After 1 hour analysis by HPLC indicated that all of the starting material was gone and that several products had formed. The reaction mixture was concentrated under vacuum. The residue was combined with dichloromethane and aqueous sodium bicarbonate. The organic layer was separated and then concentrated under vacuum. The residue was dissolved in dichloromethane and placed on a silica gel column. The column was eluted with 5% methanol in dichloromethane and then with 10% methanol in dichloromethane. The 10% methanol in dichloromethane fractions were combined and concentrated under vacuum to provide N1-[4-(4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]benzamide as a solid, m.p. 174-175° C. 1H NMR (500 MHz, DMSO-d6) δ8.48 (t, J=6.0 Hz, 1H), 8.00 (d, J=8.0 Hz, 1H), 7.78 (d, J=8.0 Hz, 2H), 7.60 (d, J=8.0 Hz, 1H), 7.50 (t, J=8.0 Hz, 1H), 7.43 (t, J=8.0 Hz, 2H), 7.39 (t, J=8.0 Hz, 1H), 7.18 (t, J=8.0 Hz, 1H), 6.50 (broad s, 2H), 4.54 (t, J=7.0 Hz, 2H), 3.32 (m, 2H), 2.91 (t, J=7.0 Hz, 2H), 1.86 (quintet, J=7.0 Hz, 2H), 1.77 (quintet, J=7.0 Hz, 2H), 1.70 (quintet, J=7.0 Hz, 2H), 1.41 (sextet, J=7.0 Hz, 2H), 0.91 (t, J=7.0 Hz, 3H); MS (CI) m/e 416 (M+H).
