Magnesium (83 mg, 3.40 mmol), 4-bromo-1-butyl-2-methylbenzene (722 mg, 3.18 mmol) and, as an initiator, catalytic amount of 1,2-dibromoethane were added to tetrahydrofuran (2.5 mL) under nitrogen atmosphere, and the mixture was stirred for 10 minutes under reflux. This mixture was cooled to 0° C., a solution of quinoline-6-carbaldehyde (100 mg, 6.36 mmol) in tetrahydrofuran (12 mL) was added thereto, followed by stirring for 1 hour at this temperature. An aqueous solution of saturated ammonium chloride was added to the reaction mixture, which was extracted with chloroform and dried over anhydrous magnesium sulfate. The solvent was evaporated, the residue was purified by silica gel column chromatography (hexane:ethyl acetate), and the title compound (152 mg, 78%) was obtained as a yellow solid.
