Procedure

A solution of 100 mg (0.13 mmol) of the resulting intermediate 2-phenyl-10,12,15,16-tetraacetoxy-6,7-dihydroxy-8-methoxy-11-methyl-9,14-dioxo-9,14-dihydronaphthaceno[1,2-g]phthalazin-1-one in 2 m of N,N-dimethylformamide is mixed, while cooling in ice, with 2 m of 1 M potassium hydroxide solution and stirred at room temperature for 2 h. The product is precipitated as a red solid (60 mg) by acidification with aqueous citric acid. The yield is 77% of theory.
