Nitric Acid → N-(6-nitro-2,3-dihydro-1H-inden-5-yl)acetamide

Participants

Reaction Steps

A mixture of 5-aminoindane (13.3 g, 0.1 mol) in 150 ml of acetic anhydride was stirred at room temperature for 3 hours. The reaction mixture was cooled to 0° C., and an ice-cooled solution of 90% nitric acid (d1.4) (8.4 g, 0.12 mol) in 15 ml of acetic anhydride (HNO3 was added dropwise to acetic anhydride with stirring at 0° C.) was added dropwise. After addition, the reaction mixture was stirred at 0° C. for 1 hour and then at room temperature overnight. The reaction mixture was poured into 800 ml of ice-water with strong stirring. The precipitate was filtered and washed thoroughly with water and dried at 40° C. to give a yellow solid (20.9 g, 95%).
