N-Aryl-N'-[(4-pyridyl)-carbonyl]thiosemcarbazides were cyclized with hydrazine to afford the 3-(4-pyridyl)-4-amino-5-arylamino-1,2,4-triazoles (2a～2c). The triazoles 2a～2c reacted with 3-formyl- chromones 3a～3d giving a series of novel compounds 3-(4-pyridyl)-4-(6-substituted chromon-3-ylme- thyl-eneamino)-5-arylamino-1,2,4-triazoles (4a～4c, 5a～5c, 6a～6c, 7a～7c). The structures of the compounds were determined by IR, 1H NMR, MS spectra and elemental analyses.

Key words: 1,2,4-triazole, synthesis, 3-formylchromone
