Procedure

A solution of 10.0 g of p-benzyloxybenzaldehyde and 15.7 g of acetylmethylenetriphenylphosphorane in 100 ml of toluene was heated under reflux for 2 hours, the solvent was then evaporated and the residual crystals were recrystallized from ether to give 9.5 g of the desired compound melting at 106°-107° C.
