Reaction Steps

To a stirred solution of 3.84 g (0.04 mole) of 3(2H)-pyridazinone, 2.33 g (0.044 mole) of acrylonitrile in 50 ml of ethanol, 1 ml of Triton-B (trimethyl benzylammonium hydroxide, 40% methanol solution) was added dropwise. The mixture was stirred for 2 hours at 60° C. and then evaporated to dryness in a vacuum on a steam bath, giving a dark orange oil. The oil was dissolved in ethanol, shaken with Norit and filtered. The filtrate was distilled. Recrystallization of the residue from ethanol and isopropyl ether gave 4.7 g (79% yield) of 3-(3-oxo-2-pyridazinyl)-propionitrile in the form of pale yellow crystals, m.p. 75°-76° C.
