The method involves vinylogous Michael addition of alkylidenemalononitrile to 2-(1,3-dioxo-1H-inden-2(3H)-ylidene)malononitrile, which formed by condensation of malononitrile and ninhydrin in the presence of Et3N, and the alc. solvent has participated in the reaction as a reagent. The method has the advantages of good yields and of not requiring a metal catalyst.
