Procedure
A quantity of 3.62 g (20 moles) of 1,8-diazafluoren-9-one and 3.2 g (0.1 mole) of hydrazine was heated in 30 ml of diethyleneglycol at 100° for 1 hour, then heated rapidly to 200 and kept there for one hour (or until TLC showed the complete disappearance of starting material). Yield 2.6 g.
