Synthesis of New Azoloazine Derivatives: New Routes to 1,2,4-Triazolo[4,3-a]pyrimidines, Pyrazolo[1,5-a]pyridines and Pyrazolo[3,4-b]pyridinones

Azoloazines are produced via reacting aminoazoles with enaminones, enaminonitriles and with ethyl alkylidene cyanoacetate.

(Substituted-phenyl)-1,2,4-triazolo[4,3-a]-pyrimidines and (substituted-phenyl)-1,2,4-triazolo[1,5-a]pyrimidines

This disclosure describes substituted 1,2,4-triazolo[1,5-a]pyrimidines and substituted 1,2,4-triazolo[4,3-a]pyrimidines which possess anxiolytic activity.
