A mixture of ethyl anthraquinone-2-carboxylate (4.83 g) 25 ml of ethanol, 50 ml of dioxane and 7 ml of hydrazine hydrate is boiled under argon for 48 hours. It is poured into water and the product is isolated by filtration and dried at 60° C. in a vacuum oven. Crystallization of the crude product (4.05 g) from dimethylformamide/chloroform gives 3.01 g of product with a melting point (m.p.) of 250° C./decomposition.
