Versuchsvorschrift

A total of 3.25 g of sodium azide was added in portions to a solution of 10.5 g of 4-chlorocarbonylphthalic anhydride in 100 ml of acetone. The mixture was allowed to stand for 17 hours at room temperature (circa 25°C) after which the yellow solution so obtained was evaporated to dryness under reduced pressure. There was thus obtained a substantially quantitative yield of 4-azidocarbonylphthalic anhydride in the form of a crystalline solid having a melting point of 100° to 103°C with decomposition.
