What is Synthesis of some novel 3,7-dimethyl-4H-pyrazolo[5,1-c][1,2,4]triazin-4-ones about?

## Abstract Some novel 3,7‐dimethyl‐6__H__‐pyrazolo[5,1‐c][1,2,4]triazin‐4‐ones were prepared **(3a‐g)**. Compounds **3a,b** were treated with hydrazines to afford various products **7a,b, 8a,b, 9 and lla,b** depending on the type of hydrazine derivative and reaction conditions. The benzoyloxyimino‐pyrazolo[5,1‐c][1,2,4]triazines **(13a,b)** were synthesized by refluxing of compounds **3a,b** with hydroxylamine hydrochloride to afford the corresponding oxime derivatives followed by treatment with benzoyl chloride.
