실험 절차
4-Bromo-7-hydroxyindan-1-one (3.06 g, 13.5 mmol) was suspended in acetic acid (20 mL), and acetic anhydride (1.66 mL, 17.6 mmol) and fuming nitric acid (838 μL, 20.2 mmol) dissolved in acetic acid (10 mL) were added. The mixture was stirred at room temperature for 3 hr. The solvent was evaporated under reduced pressure and the precipitated yellow crystals were collected by filtration to give the title compound (2.98 g, yield 79%).
