10 ml of 98% strength nitric acid dissolved in 70 ml of acetic acid were added dropwise to 50 g (0.21 mol) of 6-bromo-2-methoxynaphthalene dissolved in 350 ml of acetic acid at room temperature. The mixture was heated to 50° C. and, after the product had crystallized, cooled. The precipitate was filtered off with suction to yield 53.1 g (90%) of the product. Melting point 156°-157° C.
