N-benzamidoguanidine (4.76 g, 26.7 mmol) was used as raw material and dissolved in 40 mL of water. The reaction mixture was heated to 110 °C and refluxed for 6 hours. After completion of the reaction, the solvent was removed by distillation under reduced pressure to afford the target product 3-phenyl-1H-1,2,4-triazol-5-amine (3.0 g, 18.7 mmol, 70.1% yield).
