Versuchsvorschrift
Following the procedures outlined in Examples 1 and 3, p-methylphenylacetonitrile and diethyl oxalate are reacted in alcoholic sodium ethoxide to obtain ethyl 3-cyano-3-(p-methylphenyl)-pyruvate, m.p. 86°-88° C. The latter is reacted with p-methylphenylacetonitrile to give 2,5-di-(p-methylphenyl)-3,4-dioxoadiponitrile, m.p. 270°-272° C.
