Procedure

A mixture of 4,4'-dihydroxy-α-ethyldesoxybenzoin (4.26 g.), sodium carbonate (4.8 g.), potassium iodide (0.15 g.) and benzyl chloride (4.57 g.) in ethanol (35 ml.) and water (5 ml.) was stirred and heated under reflux for 8 hours. The mixture was cooled, filtered, and the residue washed with water and recrystallised from petrol (b.p. 100°-120° C.) to give 4,4'-dibenzyloxy-α-ethyldesoxybenzoin, m.p. 84° C.
