Procedure

3-(Diacetoxymethyl)-4-acetoxybenzyl chloride (987 g., 3.14 mole) and sodium iodide (494 g., 3.20 moles) in 3.5 liters acetone are refluxed for 6 hours. The reaction mixture is filtered, the filtrate is evaporated to dryness, triturated in ether and filtered to yield 1,162 g (91%) of 3-(diacetoxymethyl)-4-acetoxybenzyl iodide, m.p. 117°-120° C.
