실험 절차

Hydroxylamine hydrochloride (0.9 g, 13.0 mmol) was added to a suspension of 3-nitro-1,8-naphthalic anhydride (2.0 g, 8.2 mmol) in pyridine (30 mL). The mixture was refluxed for 3 hours and concentrated in vacuo to give a brown solid. The solid was suspended in water, stirred, filtered, and dried to give 2.1 g of the title compound, mp 277-279° C.
