Several new pyrazolo [1, 5-a]-S-triazine, pyrazolo [4, 5, -elpyrimidine, pyrazolo [1, 5-a] pyrimidine derivatives were synthesized via condensation of 3-antipyrinyl-5-amino-pyrazole (2) with $\beta$$-bifunctional reagents. The azo analogues of pyrazolo [1, 5-a] pyrimidines ; i. e. pyrazolo [5, 1, c]-as-triazine and pyrazolo[5, 1, -c]-as-benzotriazine were synthesized by coupling of diazotized 2-with agents containing active hydrogen.

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.

4-Arylazo-3-phenyl-5-aminopyrazoles (5a, b) and substituted hydroxythiazoles 8a, b were synthesized from the reaction of 4a, b with hydrazine hydrate and mercaptoacetic acid respectively. Compounds 5a, b and 8a, b were also obtained from coupling of 2a, b with 6 and 7, respectively. 4H-1, 4-Benzothiazine 11 was prepared from 1 and 10. The resaction of the diazonium salts 2a-c with diethyl 3-amino-2-cyanopenet-2-en-1, 5-dicarboxylate 12 was also reported.
