To a solution of 1-indanone (25.0 g, 189 mmol) in concentrated sulfuric acid (84 mL) at 0° C. was added a solution of potassium nitrate (8.33 g, 82.4 mmol) in sulfuric acid (40 mL) at a rate sufficient to maintain an internal temperature below 15° C. After the addition was complete, the reaction was allowed to stir at 0° C. for 1 hour. The reaction mixture was then poured into crushed ice and stirred vigorously for 30 minutes. The suspension was then filtered, air dried, and purified by liquid chromatography (50 ethyl acetate/toluene) to provide 18.90 g of the title compound. (56%).
