Synthesis of new pyrazole derivative with use of Michel intermadiates

In this study, the reaction of malononitrile with three ethylorthoacetat in present of ZnCl2acidic catalyst and aceticacid led to ethoxyethylene malononitrile as Michel intermediats.The reaction above intermediat with hydrazine hydrate in reflax condition new pyrazolederivatives is synthesized. The reaction pyrazole derivatives with threeethylorthoacetat ingrinding condition and in present of hydrazin hydrat, pyrazolo pyrimidine derivatives aresynthesized. In present of benzonitriles and basic catalyst, pyrazolo threazolo pyrimidinederivatives are synthesized.
