1,2,3-Triazines, IV. - Synthesis of 1,2,3-Triazinecarboxylates1,2,3-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.
