反応手順
Mixture of concentrated sulfuric acid (2.7 mL) and concentrated nitric acid (2.0 mL) was added to a solution of 4-chloro-1,8-naphthalic anhydride (3.0 g, 12.8 mmol) in concentrated sulfuric acid (10.5 mL) at 0° C. The mixture was stirred at room temperature for 2 hours and poured into ice water (50 mL). The separated solid was filtered, washed with water, and dried to give 2.1 g of the title compound (Reference: Tet., 1995;51(33):9127-9138).
