Procedure
To dry tetrahydrofuran (14 mL), n-butyl lithium (0.94 mL; a 1.6 M hexane solution) and dry acetonitrile (0.082 mL) were successively dropped at −78° C. After stirring for 30 minutes, a solution of 4-(3-phenylpropoxy)benzaldehyde (300 mg) in dry tetrahydrofuran (3 mL) was dropped into the mixture at −78° C. The reaction mixture was stirred at room temperature for 1 hour, then poured into ice-water 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 washed with a mixed solvent of diethyl ether and hexane and filtered to give the title compound (238 mg) having the following physical properties.
