Procedure
15 g of 1-isopropylamino-8-nitro-anthraquinone are stirred into a solution of 60 ml of ethylene glycol monomethyl ether and 15 g of potassium hydroxide at 55° and the mixture is further stirred at 60°-65° (approx. 1 hour being required) until only a trace of the starting material remains chromatographically detectable. The mixture is diluted with 120 ml of water and the product is filtered off, washed with water until neutral and dried in vacuo at 60°. Yield: 16.7 g.
