To provide an industrial method for producing a substituted benzoic acid compound useful as an intermediate of pharmaceutical and agricultural chemicals with high purity and high yield. A compound represented by the formula (II): (wherein Q is a 5- or 6-membered saturated heterocyclic group (the heterocyclic group may be substituted by alkyl) containing one or two of at least one type of hetero atom selected from the group consisting of an oxygen atom and a sulfur atom, or dialkoxymethyl, T is trifluoromethyl, nitro, cyano, &#x2014;SOA, &#x2014;SOA, &#x2014;PO(OA)(OA), &#x2014;COA, &#x2014;COAor &#x2014;CONAA, each of Aand Awhich are independent of each other, is a hydrogen atom, alkyl or haloalkyl, X is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, dialkylaminosulfonyl, di(haloalkyl)aminosulfonyl, nitro or cyano, Y is a chlorine atom, a bromine atom or an iodine atom, and n is an integer of from 1 to 6), carbon monoxide and a compound represented by the formula R&#x2014;OH (wherein R is alkyl) are reacted, followed by hydrolysis to obtain a compound represented by the formula (I): wherein Q, T, X and n are as defined above.

Method for producing a substituted benzoic acid compound

To provide a method for producing pyrimidine compound useful as an intermediate for agricultural chemicals or pharmaceuticals, which is simple in operation, presents high yield and produces only a small amount of by-products. The method comprises reacting a compound represented by the formula (I) with a compound represented by the formula (II) in the presence of a pyridine compound to produce a compound represented by the formula (III), a compound represented by the formula (IV) or their mixture. 

Method for producing pyrimidine compound

Because fluazinam is excellent as an active ingredient of pesticides and highly useful, it is desired to produce it efficiently in a proper form with simple operations at low cost in an environmentally friendly manner. The desired product is obtained in good yields with simple operations by using industrially advantageous reaction systems by a process comprising (1) a step of reacting ACTF and DCDNBTF in the presence of an alkali component, a solvent selected from the group consisting of ketones, nitriles, ethers and esters and a sufficient amount of water to substantially dissolve the alkali component, (2) a step of neutralizing or acidifying the reaction mixture with an acid and (3) a step of removing the solvent by distillation from the mixture containing fluazinam as the reaction product and the reaction solvent to precipitate crystals the product.
