反応手順
Triethyl orthopropionate (1000 g, 5.5 mole) and malononitrile (363 g, 5.5 mole) were combined and refluxed for 5 hours. The reaction mixture was cooled to room temperature and the residue was distilled at 125°-143° C. (3-7 mm Hg) to afford 768.1 g (93%) of (1-ethoxypropylidene)malononitrile as an orange liquid.
