반응 단계

2-(1H-imidazo[4,5-c]quinolin-1-yl)-1-butanol (3.0 g, 12.4 mmol) was added to a stirring mixture of α-bromo-p-tolunitrile (3.0 g, 15.3 mmol), sodium hydroxide (40 ml, 50%), dichloromethane (40 ml), and benzyltrimethylammonium chloride (0.02 g, 0.11 mmol). The reaction was maintained for 72 hours and then diluted with dichloromethane (100 ml) and water (100 ml). The phases were separated and the aqueous phase was extracted with additional dichloromethane (100 ml). The organic fractions were combined, washed with water, dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by flash column chromatography (silica gel, 9/1 dichloromethane/methanol, Rf 0.48) to provide 2.66 g of 4-{[2-(1H-imidazo[4,5-c]quinolin-1-yl)butoxy]methyl}benzonitrile.
