Dissolve 1,8-diaminoanthraquinone (0.476 g, 2 mmol) in N,N-dimethylformamide (20 ml). Add pyridine (0.5 ml) as catalyst in an ice bath and then add 3-chloropropioyl chloride (0.6 ml, 6 mmol). Remove the ice bath, introduce nitrogen, protect from light, and stir the solution at room temperature for one day. The reacted mixture is poured into ice water and filtered to get precipitate. The precipitate is recrystallized from ethanol to obtain orange compound 4.
