—— | 2-Chloro-5-(3,5-dimethylphenyl)-1,3,4-thiadiazole | 113111-55-0 | C10H9ClN2S | 224.714 |
A rapid and efficient microwave-assisted synthesis method for the preparation of 1-aroyl-3-(5-aryl-1,3,4-thiadiazol-2-yl)urea is described. These 1,3,4-thiadiazole aroylureas (5a–f) were identified by IR, 1H NMR, elemental analyses and N-[5-(4-methoxyphenyl)-1,3,4-thiadiazol-2-ylcarbamoyl]-2,6-difluorobenzamide was confirmed by single-crystal X-ray diffraction. The target compounds were prepared under microwave in a shorter reaction time compared with conventional heating methods.
One pot synthesis of 2-(substitutedphenyl)-3-[5-(substitutedphenyl)-1,3,4-thiadiazol-2-yl]thiazolidin-4-one was developed by the reaction of 1,3,4-thiadiazole, substituted benzaldehyde and mercaptoacetic acid. These compounds were identified by IR, 1H NMR, elemental analyses and 2-(4-methoxyphenyl)-3-[5-(3-methylphenyl)-1,3,4-thiadiazol-2-yl]thiazolidin-4-one was confirmed by single-crystal X-ray diffraction.
