2-Naphthol reacted with 3-dicyanomethylidine-1-ethyl-2-oxoindoline in absolute ethanol to afford 2-Amino-3-cyano-1'-ethylspiro{benzo[f]chromen-4,3'-indolin}-2'-one, which used as key intermediate to synthesis fused spiropolyheterocyclic derivatives of pyrimido- benzochromen and/or pyridobenzochromen nucleus incorporated indoline moiety.
