Reaction Conditions

Reaction Steps

A mixture of 17 g (60 mmol) of indeno[1,2-b]fluorene-6,12-dione, 18 g (600 mmol) of hydrazine monohydrate in 350 ml of diethylene glycol was stirred at 80° C. for 3 hours and then refluxed for 1 hour. The resulting mixture was cooled to room temperature, treated with a solution of 33 g (590 mmol) of KOH in 90 mL of water, and refluxed for 3 hours. The resulting mixture was poured into 800 ml of water, and the precipitate was filtered off, washed with water, and dried in air at room temperature to give product 13.1 g (51.6 mmol, 86%) as a yellow solid.
