Reaction Steps

To a slurry of 10.0 g (29.6 mmol) of ellagic acid dihydrate in 250 mL of pyridine was added 100 mL of acetic anhydride. The solution was heated to reflux for 3 hours. The hot solution was filtered and upon cooling, crystals formed. The crystals were filtered, washed with hexane, and vacuum dried to give 1.28 g (9.2%) of pure ellagic acid tetraacetate.
