Synthesis of Some Novel Imidazopyrazole and Pyrazolopyrimidine Derivatives

5‐Amino‐3‐anilino‐1H‐pyrazole‐4‐carbonitrile 1 was alkylated with various halo reagents under phase transfer conditions to give the corresponding imidazopyrazole derivatives 2a, 2b, 2c, 3, 4, 5, 6. Pyrazolo[1,5‐a] pyrimidine derivatives 11, 12, 13, 14 were prepared by treating compound 1 with differ...

Description
Summary:	5‐Amino‐3‐anilino‐1H‐pyrazole‐4‐carbonitrile 1 was alkylated with various halo reagents under phase transfer conditions to give the corresponding imidazopyrazole derivatives 2a, 2b, 2c, 3, 4, 5, 6. Pyrazolo[1,5‐a] pyrimidine derivatives 11, 12, 13, 14 were prepared by treating compound 1 with different dicarbonyl reagents, namely, diethymalonate, ethyl 3‐oxo‐3‐phenylpropanoate, pentane‐2,4‐dione or ethyl 3‐oxobutanoate.
