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
5-氨基-3-苯胺基-1H-吡唑-4-甲腈1用相转移条件下的各种卤代试剂,得到相应的imidazopyrazole衍生物烷基化的图2a,图2b,图2c,3,4,5,6。吡唑并[1,5-a]嘧啶衍生物11,12,13,14,通过处理化合物制备1用不同的二羰基的试剂,即,diethymalonate,3-氧代-3-苯基丙,戊烷-2,4-二酮或乙基3-氧代丁酸酯
