反応手順
A mixture of ethyl 2-cyanoacetate (120 g, 1.06 mol) and triethylorthoacetate (354 g, 2.12 mol) in glacial acetic acid (33 g, 0.53 mol) was heated at 120-130° C. overnight. The mixture was concentrated under vacuum to provide crude ethyl 2-cyano-3-ethoxybut-2-enoate. The residue was carried into the next reaction without further purification assuming 100% conversion.
