Hydrazine → HCID 12433675, compound

Participants

Reaction Steps

Following the procedure described in Example 608, Part C, 6.0 g (33 mmole) of 1,5-diazafluoren-9-one and 11.8 g (0.37 mole) of hydrazine were combined with 100 ml of diethyleneglycol and heated rapidly to 200°. The reaction was kept at this temperature for 30 minutes, then for 3 hours at 180°. Following the described workup, the crude yield was 4.69 g, m.p. 85°. Recrystallization from cyclohexane yields 4.0 g, m.p. 99°-100° of pure 1,5-diazafluorene.
