Procedure

(1-Oxo-indan-5-yl)-carbamic acid ethyl ester (0.94 g, 4.3 mmol) was dissolved in 20 ml of concentrated sulphuric acid and cooled to 0° C. using an ice-bath. Potassium nitrate (477 mg, 4.7 mmol) was added in small portions. After complete addition, the mixture was stirred for 3 hours at 0° C. and then poured onto crushed ice. The yellow precipitate was filtered off, washed thoroughly with water and dried in vacuo to give a yellow solid product (0.85, 75%).
