Reaction of ketene derivative 1 on treatment with 4-aminoantipyrine gives compound 2 with reacts with hydrazine to afford 5-amino-4-cyano-3-(p-antipyrylamino)pyrazole 3.Compound 3 on reaction with cinnamonitrile derivatives, α-acetyl ethyl cinnamate, ethyl acetoacetate, malonic acid derivatives, and chalcones furnishes respective pyrazolo pyrimidines.Diazonium salt of 3 yields pyrazolo triazines.
