1,2-Diaminoanthraquinone (1.19 g, 5 mmol) is dissolved in N,N-dimethylformamide (30 mL), and concentrated sulfuric acid (0.1 mL) is further added thereinto after acetophenone (0.5 ml, 6 mmol) is added thereinto. After mixing and reacting in room temperature for 72 hours, the reacted mixture is transferred into icy water (200 mL) for precipitation. The precipitate is collected and recrystallized by hot alcohol, so as to obtain the black compound 21, and the production rate is 28%.
