2-Amino-5-(1-phenyl-3-methyl-5-chloropyrazol-4-yl)-1,3,4-thiodiazole (1) has been prepared by the reaction of 1-phenyl-3-methyl-5-chloropyrazol-4-carboxylic acid with aminothiourea in the presence of phosphorus oxychloride. Then a series of novel 1-[(un)substituted benzoyl]-3-[5-(1-phenyl-3-methyl-5- chloropyrazole-4-yl)-1,3,4-thiadiazol-2-yl]-thioureas (3a～3j) have been synthe-sized by the reaction of compound 1 with (un)substituted benzoyl isothiocyanates (2) by means of ultrasonic radiation heating method and ordinary method. The structures of these compounds were confirmed by elemental analysis, IR and 1H NMR spectra.

Key words: (un)substituted benzoylthiourea, ultrasonic radiation, 1,3,4-thiodiazole, synthesis, pyrazole
