A method of easily synthesizing a cyclopropylphenol derivative. The method, which is a process for producing a cyclopropylphenol derivative represented by the general formula (10): [wherein R1, R2, R3, and R4 each independently is hydrogen, etc.; Z is hydrogen, etc.; and Y1, Y2, and Y3 each independently is hydrogen, etc.], comprises reacting a compound represented by the general formula (7): [wherein the symbols have the same meanings as defined above; X is halogeno; and V is hydrogen, etc.] with a metal, metal salt, or organometallic compound represented by the general formula M2 (8) to obtain a compound represented by the general formula (9): [wherein the symbols have the same meanings as defined above]. When V is a -W-R5 group, hydrolysis is further conducted. Thus, a compound of the general formula (10) is obtained.

Procédé servant à synthétiser facilement un dérivé de cyclopropylphénol. Le procédé, lequel est un procédé servant à produire un dérivé de cyclopropylphénol représenté par la formule générale (10) : [où R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP> et R<SUP>4</SUP> sont chacun indépendamment un hydrogène, etc. ; Z est un hydrogène, etc. ; et Y<SUP>1</SUP>, Y<SUP>2</SUP> et Y<SUP>3</SUP> sont chacun indépendamment un hydrogène, etc.], comprend de faire réagir un composé représenté par la formule générale (7) : [où les symboles ont les mêmes significations que celles définies ci-dessus ; X est un halogéno ; et V est un hydrogène, etc.] avec un métal, un sel d'un métal ou un composé organométallique représenté par la formule générale M<SUP>2</SUP> (8) pour obtenir un composé représenté par la formule générale (9) : [où les symboles ont les mêmes significations que celles définies ci-dessus]. Lorsque V est un groupe -W-R<SUP>5</SUP>, on effectue encore une hydrolyse. Ainsi, on obtient un composé de formule générale (10).
