Procedure

Following the procedures outlined in Examples 1 and 3, p-methoxyphenylacetonitrile is reacted with diethyl oxalate in alcoholic sodium ethoxide solution to give ethyl 3-cyano-3-(p-methoxyphenyl)pyruvate which is then similarly reacted with phenylacetonitrile to yield 2-(p-methoxyphenyl)-5-phenyl-3,4-dioxoadiponitrile.
