A new convenient synthesis of 3-hetaryl-pyrazolo[5,1-c][1,2,4]triazines
Reactions of enaminones 2 with diazotized 5-amino-3-phenylpyrazole provide a convenient route to 3-[(4,5-disubstituted-pyrazol-3-yl)carbonyl]-pyrazolo[5,1-c][1,2,4]triazines. Condensation of the latter with hydrazine hydrate yielded the title compounds. The structures of the compounds prepared were...
