| Abstract: | 2-Amino-4-aryl-3-cyano-5-methyl-7-phenylpyrazolo5,4-b]-γ-pyran derivatives were synthe-sized by the reaction of aromatic aldehydes, malononitrile and 4,5-dihydro-3-methyl-5-oxo-1- phenylpyra-zole in ionic liquid bmim]BF4], which provided a fast, efficient and clean method. The structures of the product were characterized by IR, 1H NMR spectra and elemental analyses. |
