Versuchsvorschrift
65.1 g (0.36 mol) of 4-aminophthalic acid in 500 ml of dioxane are reacted with 43.12 g (0.38 mol) of glutaric anhydride, in the manner described in Example 9, to give 4-glutaramidyl)-phthalic acid, and the latter is subsequently cyclised. 70 g (75% of theory) of 4-(glutarimidyl)-phthalic anhydride of melting point 220°-222° C. are obtained.
