Versuchsvorschrift

Four grams (18.9 mmol) of α-cyano-β-ethoxy-N-ethoxycarbonylacrylamide is dissolved in hot ethanol/toluene. To this is added, portionwise, 4 g of 2,4,6-trichlorophenylhydrazine. The mixture is heated to reflux for three days. Cooling of the mixture and evaporation of the solvent gives the crude product, which is recrystallized from ethanol (3X) to yield α-cyano-β-(2,4,6-trichlorophenylhydrazino)-N-ethoxycarbonylacrylamide, m.p.=161° (dec.).
