Reactions with Heterocyclic Amidines (V). Synthesis of some new imidazo[l, 2-b] pyrazole,pyrazolo[5,1-C]-1,2,4-triazine and pyrazolo [5, 1-c]-1,2,4-triazole derivatives

Several new imidazo [1, 2-b] pyrazole, pyrazolo [5, 1-c]-1, 2, 4-triazine and pyrazolo [5, 1-c] triazole derivatives were prepared from the reaction of 3-antipyrinyl-5-aminopyrazole or its diazonium salt with .alpha.-chloroacetyl derivatives.
