Synthesis of 4-phenyl-1,2,4-triazoline-5-one and 3,4-diphenyl-1,2,4-triazoline-5-one N1-derivatives

In the reaction of formic and benzoic acids hydrazide with isocyanates there were obtained semicarbazide derivatives which due to the cyclization in the basic medium gave 1,2,4-trazoline-5-one derivatives [Ia, b]. These compounds reacting with ethyl bromoacetate, ethyl chloroformate, allyl bromide, acetic anhydride, benzoyl chloride and in the aminomethylation and cyanoethylation reactions gave N1-derivatives of 1,2,4-triazoline-5-one [IIa, b-XIIa, b].
