Versuchsvorschrift

0.50 g of 1-benzyloxycarbonylaminoanthraquinone, 25 ml of ethanol and 25 ml of 50% strength aqueous sodium hydroxide solution were heated under reflux for 6 hours and the solution was then concentrated in vacuo. The residue was taken up in chloroform/water, the phases were separated and the organic phase was washed twice with water. The organic phase was concentrated in vacuo and 0.30 g of 1-aminoanthraquinone (99% pure; 95% of theory) was obtained.
