実験手順

0.47 g of 1-benzyloxycarbonylamino-1,4,4a,9a-tetrahydroanthraquinone, 6 mg of copper(I) chloride and 10 ml of pyridine were stirred at 25° C. for 30 hours under a gentle stream of air and the solution was then concentrated in vacuo. The residue was taken up in chloroform, the solution was extracted with 2N hydrochloric acid and the organic phase was concentrated in vacuo. 0.41 g of 1-benzyloxycarbonylaminoanthraquinone (86% pure; 76% of theory) was obtained.
