실험 절차

Methanesulfonic anhydride (0.19 g, 1.1 mmol) was added to a stirring solution of 1-(4-aminobutyl)-2-(4-methoxybenzyl)-1H-imidazo[4,5-c]quinolin-4-amine (0.4 g, 1.07 mmol), dichloromethane (75 ml) and acetonitrile (100 ml). The reaction was maintained at room temperature for 60 hours. 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 0.3 g of N-[4-(4-amino-2-(4-methoxybenzyl)-1H-imidazo[4,5-c]quinolin-1-yl]butyl]methanesulfonamide as a white solid, m.p. 78.1–79.5° C. 1H NMR (300 MHz, DMSO-d6) δ 7.99 (d, J=7.6 Hz, 1H), 7.62 (dd, J=8.3, 1.2 Hz, 1H), 7.42 (m, 1H), 7.27–7.21 (m, 3H), 6.98 (t, J=5.7 Hz, 1H), 6.89 (d, J=8.7 Hz, 2H), 6.58 (broad s, 2H), 4.45 (broad s, 2H), 4.33 (s, 2H), 3.72 (s, 3H), 2.87 (m, 5H), 1.55 (broad s, 2H); MS (CI) m/e 454 (M+H).
