Abstract:
In view of the biological activities of 5-aminopyrazoles, e.g. tranquilizing and analgesic properties, some of new fused pyrazolopyrimidines and pyrazolotriazines were synthesized. 5-Amino 3-substituting group 4-cyano (or ethoxycarbonyl) pyrazoles 2 were prepared via the reaction of 1 with hydrazine hydrate in ethanol at room temperature (Scheme 1).
