Procedure
A mixture of isatoic anhydride (8.54 g), benzyl alcohol (6.0 g), 4-dimethylaminopyridine (6.7 g), dimethylformamide (17 ml), triethylamine (5.28 g), and methylene chloride (160 ml) is refluxed overnight, diluted with an equal volume of ethyl acetate and washed with water, brine, and water. The organic solution is dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude product is purified by flash chromatography eluting with 30% ethyl acetate in hexane to give the desired product.
