METHOD FOR PRODUCING A SUBSTITUTED BENZOIC ACID COMPOUND

Provided is an industrial production method with which a substituted benzoic acid compound that is useful as a drug or agrichemical intermediate is obtained with high purity and at a high yield. A compound represented by formula (II) (where Q is a 5 or 6 member saturated heterocycle group (where the heterocycle group is optionally substituted by alkyl) comprising one or two hetero atoms of at least one type selected from the group consisting of oxygen atoms and sulfur atoms, or a dialkoxymethyl; T is trifluoromethyl or the like; X is a halogen or the like; Y is a hydrogen atom, bromine atom, or iodine atom; and n is an integer between 1 and 6.) carbon monoxide and a compound represented by formula R OH (where R is an alkyl group) are reacted and then hydrolyzed to produce a compound represented by formula (I) (where Q T, X, and n are the same as previously defined).
