実験手順

1,5-dichloroanthraquinone (1.0g), n-octanesulfonamide (0.77g), potassium carbonate (1.0g), cupric acetate monohydrate (1.0g) and chlorobenzene (15ml) were refluxed for 4 hours. The solvent was evaporated at reduced pressure and the residue was extracted with toluene. After filtration the extract was separated by chromatography on silica using toluene as eluent to give the desired product as the second fraction.
