A Convenient Synthesis of 1-Aryl-3-methyl-1,2,4-triazolin-5-ones From the Reaction Between Acetone Arylhydrazones and Acetyl Isocyanate

The reaction of acetone arylhydrazones with acetyl isocyanate gave the corresponding 4-acetyl-1-aryl-3,3-dimethyl-1,2,4-triazolidin-5-ones which eliminated acetone upon hydrolysis to give 1-aryl-3-methyl-1,2,4-triazolin-5-ones.The above transformation can be achieved in one pot by a simple solvent swap.
