Malononitrile → HCID 22320152, compound

Participants

Reaction Steps

A solution of malononitrile (19.8 g, 300 mmol) and 2-hydrazinopyridine (16.4 g, 150 mmol) in ethanol (300 mL) was heated under reflux for 12 hours. The solution was cooled to room temperature, and the resulting crystals were collected by filtration. The crystals were purified by silica gel column chromatography (chloroform to 2% methanol/chloroform) to give the title compound (12.5 g, 37% yield).
