2‐Oxo‐3‐(indol‐3‐yl)propanonitrile 2 condensed with dimethylformamide dimethylacetal to yield the enaminonitrile 3 . The latter reacted with 4‐chloroaniline to yield the 4‐chlorophenylaminoacrylonitrile 5 . Reaction of 3 with hydrazine hydrate led to formation of pyrazole‐4‐carbonitrile 6 . Compound 3 reacted with ethyl acetoacetate in refluxing acetic acid and in presence of ammonium acetate to yield the indolylpyridine 10 . Enamine 3 reacted with 5(1 H )‐aminotriazole 13 and 3(5)‐aminopyrazole 17 to yield the pyrimidine derivatives 15 and 19 , respectively.
