Reaction Steps
1.9 g of 2-phenyl-benzo[e][1,3]oxazin-4-one are refluxed in 75 ml of ethanol with 1.0 g of hydrazine hydrate. After about 1 hour the solvent is distilled off in vacuo and the residue remaining is stirred into water. The solid formed (3-(2-hydroxyphenyl)-5-phenyl-1,2,4-triazole) is used in the next step without further purification. Yield: 0.5 g (25%).
