Reaction Steps

To a solution of 2-chloropyridine-4-carbonitrile (20.0 g, 144 mmol) in 1-butanol (150 mL) was added 1 M solution of hydrazine hydrate in THF (303 mL, 303 mmol) dropwise at rt. It was then heated at 60° C. overnight. The mixture was concentrated, and the residue was purified by flash column chromatography (CH2Cl2/MeOH=20/1) to afford the title compound (3.5 g, 18%) as a white solid. [M+H] Calc'd for C6H6N4, 135. Found, 135.
