ABSTRACT:
This invention provides a process for producing an epoxytriazole derivative represented by formula (2):(wherein R and Ar are defined below),which comprises a step including a reaction of an epoxy derivative represented by formula (1′):(wherein R represents a hydrogen atom or C1-12 alkyl group and Ar represents an aromatic group optionally substituted by a halogen atom(s) or trifluoromethyl group(s), and X′ represents a hydroxy group or leaving group),with 1,2,4-triazole in the presence of a base and water.
