500 mL of dimethylformaldehyde was added to a mixture of 10 g of purified acenaphthenequinone and 84 g of 3,4-diaminobenzoic acid. The reactant continued to be stirred at room temperature for 21 hours. The precipitate was filtered to obtain a crude composition. This crude composition was dissolved in heated dimethylformamide, filtered again and purified by washing in dimethylformamide and water.
