1,2,3‐Triazines, IV. – Synthesis of 1,2,3‐Triazinecarboxylates 1,2,3‐Triazinecarboxylates 5 have been prepared by rearrangement of the cyclopropenyl azides 6 as well as by oxidation of the 1‐aminopyrazoles 9 , 10 . Reaction of 1‐aminopyrazole‐5‐carboxylates 10 with triethyl orthoformate ( 19 ) and ammonia affords pyrazolo[3,2‐ f ][1,2,4]triazin‐4‐ones 18 .
