Preparation of 2-chloro-4-hydrazino Benzonitrile
At 25° C., to a reaction vessel were added 40 g of 2-chloro-4-fluorobenzonitrile (1.0 eq), 45.5 g of hydrazine hydrate (3.0 eq, 85%) and 200 g of absolute ethanol.
The mixture was warmed up to 80° C. and reacted for 3 hours. 400 g of water was added.
The mixture was cooled down to 20° C., stirred, and filtered by suction.
The filter cake was rinsed with ethanol, and the wet filter cake was dried under vacuum to produce 2-chloro-4-hydrazino benzonitrile (about 40 g) as a white solid in a yield of about 92%.
Mass spectrum (M+1): 168
1H-NMR (DMSO-d6, 400 MHz): δ 8.09 (1H, s), 7.49 (1H, d), 6.91 (1H, s), 6.69 (1H, d), 4.40 (2H, s).
