Procedure

By employing the procedures set forth in Examples 1 and 3, p-fluorophenylacetonitrile is reacted with diethyl oxalate in alcoholic sodium ethoxide to give ethyl 3-cyano-3-(p-fluorophenyl)-pyruvate. Reaction of the latter under similar conditions with p-fluorophenylacetonitrile results in 2,5-di-(p-fluorophenyl)-3,4-dioxoadiponitrile.
