Hydrazine hydrate (1:1) → HCID 135504036, compound

Participants

Reaction Steps

With stirring, hydrazine monohydrate (1.44 ml, 30 mmol) was added at 25° C. to a solution of the bromide (X) (2.20 g, 10 mmol) in water (80 ml). The reaction mixture was heated to reflux, cooled to room temperature and, for crystallization, allowed to stand for several hours. The crystals were filtered off, washed with water and dried in the air, giving the hydrazine (XI) (1.08 g, 63%) as a white solid of melting point 264-266° C.
