A method for producing a 1,2,4-triazole compound involves reacting an amide compound represented by formula (2) with a hydrazide compound represented by formula (3) in a solvent in the presence of a Lewis acid and a Lewis base, thereby obtaining a 1,2,4-triazole compound represented by formula (1):
R
1
represents an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, an aryloxy group, a monovalent heterocyclic group or a substituted amino group, R
2
and R
3
each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, a monovalent heterocyclic group or a substituted amino group, and Ring A and Ring B each independently represent an aromatic hydrocarbon ring or an aromatic heterocyclic ring.
一种制备1,2,4-三唑化合物的方法,涉及在溶剂中,存在Lewis酸和Lewis碱的情况下,将由式(2)表示的酰胺化合物与由式(3)表示的肼化合物反应,从而得到由式(1)表示的1,2,4-三唑化合物:其中,R1表示烷基,环烷基,烷氧基,环烷氧基,芳基,芳氧基,一价杂环基或取代氨基,R2和R3各自独立地表示氢原子,烷基,环烷基,芳基,一价杂环基或取代氨基,环A和环B各自独立地表示芳香族碳环或芳香族杂环。
