Procedure

A round bottom flask was charge with a stir bar, 2-(4-chloro-2-methyl-1H-imidazo[4,5-c]quinolin-1-yl)ethanol (3.9 g, 14.9 mmol), dichloromethane (125 mL), aqueous sodium hydroxide (50%, 125 mL), benzyltrimethylammonium chloride (0.55 g, 0.003 mmol) and stirred vigorously at ambient temperature. To this mixture was added cinnamyl bromide (8.8 g, 44.71 mmol) as a solid. After 45 minutes the solution was clear and the reaction was judged complete. The solution was poured into ice water (200 mL), the organic layer separated and was drawn off. The aqueous solution was extracted with dichloromethane (4×). The organic layers were combined, washed with brine, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting orange oil was purified by chromatography over silica gel (dichloromethane, followed by 98/2 dichloromethane/methanol). The resulting oil was triturated with ethyl ether and the resulting solid was collected by filtration and dried to provide 4.22 g of 4-chloro-2-methyl-1-(2-{[(2E)-3-phenylprop-2-enyl]oxy}ethyl)-1H-imidazo[4,5-c]quinoline as a white solid.
