실험 절차
A solution of 21.2 g of 3-(p-benzyloxyphenyl)propionaldehyde and 30.9 g of acetylmethylenetriphenylphosphorane in 120 ml of tetrahydrofuran was heated under reflux for 4.5 hours, the solvent was then evaporated and the residual crystals were recrystallized from a mixture of n-hexane and ether (5:1) to give 26.1 g of the desired compound melting at 70°-72° C.
