Abstract

PURPOSE: The reaction of aminoanthraquinone with an alkaline condensation agent is conducted in the presence of a specific amount of dimethylsolfoxide to produce high-quality title compound in high yield.
CONSTITUTION: The reaction between 1-aminoanthraquinone and an alkaline condensation agent as potassium hydroxide is conducted in the presence of dimethylsulfoxide in an amount of 0.1W2.5 times the quantity of the aminoanthraquinone and an oxidizing agent, when necessary, an inert solvent at 80W140°C.
EFFECT: Troublesome recovery process can be eliminated since the amount of dimethylsulfoxide employed is little and further the amount of caustic alkali used can be largely reduced.
