Procedure

A solution of 50 g (0.2 mol) of 4-benzyloxybenzaldehyde in 500 mL of acetone was diluted with 500 mL of water. To the cloudy emulsion which formed was added 20 mL of 1N sodium hydroxide and the mixture stirred at room temperature for 20 hours. The solids which precipitated were recovered by filtration. Recrystallizaton from methanol gave the above named product, as a tan flasky solid, in a yield of 51 g (87 percent of theoretical). The product melted at 102°-109° C.; 1H NMR (CDCl3): δ 2.29 (s, 3H, CH3 --), 5.04 (s, 2H, --CH2 --), 6.48-7.52 (m, 11H, ArH's and --CH=CH--).
