摘要：

A method comprising an oximation step of reacting a formylalkenylcyclopropanecarboxylic acid ester represented by the formula (1): (wherein, R 1 represents an alkyl group optionally having substituent(s) or halogen atom(s), and R 2 represents an alkyl group optionally having substituent(s) or a benzyl group optionally having substituent(s).) and hydroxylamine in a solvent in the presence at least one compound selected from the group consisting of carboxylic acids and carboxylic acid metal salts, to produce a hydroxyiminoalkenylcyclopropanecarboxylic acid ester represented by the formula (3): (wherein, R 1 and R 2 are as defined above.).
