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):
R1 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, R2 and R3 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.
