Synthesis of novel pyrazolo[3,4-d][1,2,3]Triazines

Studies have been conducted of the reactions of 7-phenyl-3,7-dihydro-4H- pyrazolo[3,4-d]-[1,2,3]triazin-4-one with alkyl halides and formaldehyde, that occurred with retention of the pyrazolotriazine structure. Ethyl 2-(4-oxo-7-phenyl-4,7-dihydro-3H-pyrazolo[3,4-d][1,2,3]triazin-3-yl)-acetate was prepared by the reaction of 7-phenyl-3,7-dihydro-4H-pyrazolo[3,4-d][1,2,3] triazin-4-one with ethyl chloroacetate. It was used to synthesize the corresponding hydrazide with the aim of introducing the pyrazole or 1,3,4-oxadiazole fragments in the side chain of a bicyclic system.
