Procedure

m-Xylylene dichloride (25.0 g, 143 mmol) and potassium acetate (34.0 g, 171 mmol) were suspended in acetone (125 ml). To the suspension was added benzyltriethylammonium chloride (4.8 g) and the mixture was refluxed for 2.5 hr. The reaction mixture was cooled and filtered. The solvent was evaporated and toluene (50 ml) was added. The toluene layer was washed with water (50 ml) and saturated brine (50 ml) and the solvent was evaporated to give m-xylylene glycol diacetate (31.3 g, 98.7%) as an oil.
