微波辐射下, 二氨基硫脲与乙酸反应制得3-甲基-4-氨基-1,2,4-三氮唑-5-硫酮(1), 在无水乙醇中以三乙胺作为反应的缚酸剂, 1与[二-(4-氟苯基)]甲基氯经微波辐射制得中间体3-甲基-4-氨基-5-[二-(4-氟苯基)]甲硫基-1,2,4-三氮唑(2), 然后中间体2与芳香醛经缩合反应制得了10个Schiff碱3a～3j. 合成的10个目标化合物通过熔点测定和质谱、红外光谱、核磁共振氢谱分析、元素分析对其结构进行确证.

Under microwave irradiation conditions, ten Schiff bases 3a～3j have been synthesized. Firstly thiocarbazide was reacted with acetic acid to prepare 4,5-dihydro-3-methyl-4-amino-1,2,4-triazole-5-thione (1). Then compounds 1 reacted with [bi-(4-fluorophenyl)]methyl chloride in the presence of triethylamine and ethanol to form the key intermediate 2. The target compounds 3a～3j were synthesized by the condensation between substituted benzaldehyde and the intermediates 2 in acetic acid medium. The structures of target compounds have been confirmed by IR, 1H NMR, MS techniques and elemental analysis.

Key words: 1,2,4-triazole Schiff bases, [bi-(4-fluorophenyl)]methyl chloride, organic synthesis, microwave irradiation
