実験手順

Ethyl 3-cyano-3-phenylpyruvate (50.0 g., 0.23 mol.) and 41.0 g. (0.35 mol.) of phenylacetonitrile were added to an alcoholic solution of sodium ethoxide [prepared from 13.4 g. (0.58 g.-atom) of sodium and 360 ml. of absolute ethanol] and the resulting yellow solution was refluxed for 1.75 hours. The cooled solution was diluted with 700 ml. of water and acidified by slow addition of acetic acid. After further cooling in ice, the suspension was filtered and the solid was washed with water and dried to give 2,5-diphenyl-3,4-dioxoadiponitrile, m.p. 284°-286° dec.
