2-Amino-5-(2-phenyl-1,2,3-triazol-4-yl)-1,3,4-thiodiazole(1) was prepared by the reaction of 2-phenyl-1,2,3-triazole-4-carboxylic acid with aminothiourea in the presence of phosphorus oxychloride.Then a series of N-[5-(2-phenyl-1,2,3-triazol-4-yl)-1,3,4-thiodiazol-2-yl]-N'-aroylthioureas was synthesized by the reaction of compound 1 with aroyl isothiocyanates by means of ultrasonic radiation method and ordinary method.The reaction time for the first method was about 12.5% that of the second one,and the yield was increased by 4%~17%.The side products were at the same time reduced.The structures of these compounds were confirmed by elemental analysis,MS,IR and ¹H NMR spectroscopies.
