4-甲基-1,2,3-噻二唑-5-羧酸酰肼 | 4-methyl-4,5-dihydro-1,2,3-thiadiazole-5-carbohydrazide | 75423-15-3 | C4H6N4OS | 158.184 |
A series of novel urea derivatives containing the 1,2,3-thiadiazole moiety were synthesised using microwave-assisted condensation reactions of 4-methyl-1,2,3-thiadiazole-5-carbohydrazide with various substituted isocyanatobenzenes in acetonitrile. Their chemical structures were characterised by 1H NMR, MS and elemental analysis. This method provides several advantages such as high yields, facile work-up and is environmentally friendly.
