Procedure

A mixture containing 2-(chloromethyl)quinoline hydrochloride (15 g), 4-hydroxybenzaldehyde (8.56 g) and anhydrous potassium carbonate (29 g) was heated under reflux in acetone (300 mL) for 86 h. After cooling to room temperature, ether (400 mL) was added and the mixture was filtered on celite. The filtrate was evaporated to dryness under reduced pressure and purified by flash chromatography using 15% ethyl acetate/hexane. The title compound was obtained after recrystallization from ethyl acetate/hexane m.p. 89°-90°.
