Following the procedure described in Example 608, Part C, 3.45 g (19 mmole), of 4-azafluoren-9-one, 6.8 g (0.213 mole) of hydrazine in 50 ml of diethyleneglycol were combined and heated to 205° over a 30 -minute period. TLC showed no remaining starting material. Identical workup yielded 2.33 g of pure 4-azafluorene, Rf-0.46 (hexane ethylacetatetriethylamine, 29.75:69.46:0.79).
