Procedure

2-[5-(1,3-Dioxolan-2-yl)furan-2-yl]-3,5-bis(methoxymethoxy)benzaldehyde (135 mg, 0.374 mmol) was dissolved in diethyl ether (10 mL), and the solution was cooled to −78° C., and then cyclohexane/diethyl ether solution of 1.06 mol/L phenyllithium (0.54 mL, 0.57 mmol) was added thereto and stirred at the same temperature for 1 hour. Water was added to the reaction mixture, and extracted with diethyl ether. The organic layer was washed with aqueous saturated sodium chloride solution, then dried over anhydrous sodium sulfate, and the solvent was extracted out under reduced pressure. The resulting residue was purified through preparative thin-layer chromatography (chloroform/methanol=50/1) to obtain 1-{2-[5-(1,3-dioxolan-2-yl)furan-2-yl]-3,5-bis(methoxymethoxy)phenyl}-1-phenylmethanol (93.9 mg, 57%).
