6-Nitroquinoline (I) reacts with ethyl cyanoacetate in the presence of potassium cyanide or sodium hydride to produce 6-ethoxalylaminoquinoline-5-carbonitrile (IIa) and diethyl 2-cyano-3-(5-cyano-6-quinolylamino)fumalate (III). Reactions with some other active methylene compounds in the presence of potassium cyanide also afforded respective products corresponding to IIs (IIb, IIc and IId).
