실험 절차

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 (3 X) to yield α-cyano-β-(2,4,6-trichlorophenylhydrazino)-N-ethoxycarbonylacrylamide, m.p. =161° (dec.).
