실험 절차

To a tetrahydrofuran solution (1 L) of 1-bromo-4-[2-(methoxymethoxy)ethyl]benzene (50.2 g, 0.205 mol) was added dropwise under nitrogen atmosphere at −78° C. a 2.6 M n-butyllithium solution in hexane (78.8 mL, 0.205 mol), and the mixture was stirred for 15 minutes at the same temperature. Then a tetrahydrofuran solution (150 mL) of 4-benzyloxy-5-bromo-2-methyl benzaldehyde (56.9 g, 0.195 mol) was added dropwise over an hour, and the mixture was stirred for 30 minutes at the same temperature. To the reaction solution was added a saturated aqueous solution of ammonium chloride, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of ammonium chloride and brine, and dried with anhydrous magnesium sulfate. The drying agent was filtered off, and the solvent was evaporated under reduced pressure to obtain [4-(benzyloxy)-5-bromo-2-methylphenyl][4-[2-(methoxymethoxy)ethyl]phenyl]methanol.
