Vorschrift

Bromine (8.2 g, 51.3 mmol) was added to a solution of 1,8-naphthalic anhydride (10.0 g, 50.5 mmol) in 70% nitric acid (200 mL) at 25° C. The mixture was stirred at 70° C. for 2 hours and cooled overnight. The solids that separated were filtered, washed with water, and dried to give 2.0 g of the title compound (Reference: J. C. S., 1938:1764-1767).
