PROBLEM TO BE SOLVED: To provide a method for safely, simply and industrially producing a 5-alkyl-4-carboxylate-1,2,3-triazole useful as an intermediate for medicines, agrochemicals, and the like. SOLUTION: This method for producing the 5-alkyl-4-carboxylate-1,2,3-triazole derivative represented by formula (2) (R<1> and R<2> are each a 1 to 5C alkyl) is characterized by reacting a 3-acylhydrazon-2-hydroxyiminobutanoate derivative represented by formula (1) (R<3> is H or a 1 to 4C alkyl) with a condensing agent.
