32.83 g (0.2 mol) of 5-norbornene-2,3-dicarboxylic acid anhydride and 400 Ml of glacial acetic acid were put into a 1000 Ml flask, heated to 110° C. to dissolve, and then 41.1 g (0.3 mol) of excess 4-aminobenzoic acid was added thereto to form a mixed solution. Subsequently, the mixed solution was stirred and reacted for 2 hours, and was then precipitated at room temperature. Subsequently, the precipitate was washed with glacial acetic acid and water, and was then dried in a vacuum oven at 60° C. to prepare 4-nedimide benzoic acid in 95% yield.
