stituted 4-aminoimidazo [1, 5-a]-1, 3, 5-triazines by treatment with formamidine at 20 OC.'It was of interest to learn whether the scope of the reaction could be broadened to include the conversion of 4-substituted 5-amino-4-cyano-4H-1, 2, 3-triazoles to 8-substituted 4-amino-1, 2, 3-triazolo-[1, 5-~]-1, 3, 5-triazines. In this category, 5-amino-4-cyano-4-methyl-4H-1, 2, 3- triazole (1) was considered a representative candidate for translocative rearrangement.(1) ...
