Procedure
To a solution of 4-(3-phenylpropoxy)benzaldehyde (10.4 g) in dry tetrahydrofuran (100 mL), a solution of bromo(vinyl) magnesium in tetrahydrofuran (14%, about 1 M) was added at 0° C. After stirring for 15 minutes, the reaction mixture was added to a cold saturated aqueous ammonium chloride solution and extracted with ethyl acetate. The organic layer was successively washed with water and a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=20:1 to 3:1) to give the title compound (10.01 g) having the following physical properties.
