실험 절차
To a solution of 310 mg (1.21 mmol) of 8H-5,9,11-trioxabenzo[de]anthracene-4,6-dione (from Example T3) in 4 mL pyridine was added 260 mg (3.74 mmol) of hydroxylamine hydrochloride and the reaction mixture refluxed for 2 hours and poured into 50 mL water while hot. The precipitate was isolated, washed with water, and dried to yield 190 mg of the title compound, mp 314-315° C.
