10 ml (75 mmol) of α-tetralone was added dropwise to 7.6 g (75 mmol) of potassium nitrate dissolved in 75 ml of concentrated sulfuric acid (at -10° C.). The resulting mixture was poured onto ice and the precipitate was suspended in ether. The precipitate (the 7 nitro isomer) was filtered off and the ether solution was evaporated. The residue was purified by column chromatography on silica gel. Yield: 4.7 g of the title compound, M.p. 94°-96° C.
