Reaction Conditions

Reaction Steps

Potassium 4-bromo-naphthalene-1-sulfonate (1.38 g, 4.24 mmol) was added portionwise over 20 minutes to 90% nitric acid (2 mL), which was cooled in a methanol/ice bath to approximately −15° C. After 1.5 hours, the mixture was placed in a refrigerator for 20 hours. Diethyl ether (20 mL) was added and the precipitated solid was filtered, washed with ether (100 mL) and isopropanol (20 mL), and dried under a stream of nitrogen to give the title compound as an approximately 4:1 mixture of the 5- and 8-nitro isomers (1.25 g).
