Reaction Steps

A mixture of 6-chloro-nicotinonitrile (2.77 g, 20 mmol) and hydrazine hydrate (15 mL) was stirred at 100° C. for 3 h and evaporated. The residue was suspended in ether and filtered, then suspended in sodium bicarbonate solution and filtered, washing with water, and dried to provide 6-hydrazino-nicotinonitrile (1.25 g, 46% yield) as a tan solid. 1H-NMR (DMSO-d6, 500 MHz) 8.59 (s, 1H), 8.35 (s, 1H), 7.74 (d, 1H), 6.75 (s, 1H), 4.44 (s, 2H) ppm; MS (FIA) 135.1 (M+H).
