実験手順

A 100ml round bottom flask, equipped with a magnetic stirrer and cooling condenser, was charged with 1,8-dichloroanthraquinone (1.0g), benzylsulfonamide (4.0g), copper acetate monohydrate (1.0g), potassium carbonate (1.4g) and chlorobenzene (20ml). This mixture was refluxed for 2.0 hours and cooled, whereupon methanol (100ml) was added to induce precipitation. The solid was collected, extracted with dichloromethane, treated with charcoal, and recrystallized from a mixture of methanol and dichloromethane to afford a yellow product.
