摘要
N-芳基-N'-[(4-吡啶基)羰基]氨基硫脲用85%的水合肼环化,得到3-(4-吡啶基)-4-氨基-5-芳氨基-1,2,4-三唑(2a～2c).然后再与3-甲酰基色酮(3a～3d)反应,制备得到了一系列新化合物:3-(4-吡啶基)-4-(6-取代色酮-3-基亚甲氨基)-5-芳氨基-1,2,4-三唑(4a～4c,5a～5c,6a～6c,7a～7c).化合物的结构经元素分析,IR,1HNMR和MS确证.
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-formylchromones 3a-3d giving a series of novel compounds 3-（4-pyridyl）-4-（6-substituted chromon-3-ylmethyleneamino）-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.
