Reaction Steps
In a similar manner, 4-[(2-methyl-2H-benzotriazol-5-yl)hydrazono]-4H-pyrazole-3,5-diamine was prepared from 2-methyl-2H-benzotriazol-5-ylamine (which was prepared from methyl-5-nitro-2H-benzotriazole (2.0 g) in a manner similar to that described above) (0.24 g), malononitrile (0.2 g) and hydrazine hydrate (0.2 g) to yield 0.181 g. MS (m/z, ES+): 258 (M+1, 100%).
