Abstract: The present invention is a method for producing a 1-substituted-3-fluoroalkylpyrazole-4-caroxylic acid ester, the method comprising a step of adding, to a first reaction liquid containing an alkyl hydrazine and a first organic solvent, a second reaction liquid containing an acyl acetic acid ester derivative and a second organic solvent in 0.5 to 30 hours to react the first reaction liquid with the second reaction liquid at a reaction temperature of ?5 to 80° C. under stirring in the absence of a base and an acid, wherein the first organic solvent and the second organic solvent are each at least any one of benzene, toluene, xylene, chlorobenzene, dichlorobenzene, ethyl acetate, butyl acetate, and dimethyl carbonate, a total mass of the first organic solvent and the second organic solvent is 1 to 60 times a mass of the acyl acetic acid ester derivative, and an amount of the first organic solvent in a total amount of the first organic solvent and the second organic solvent is 40 to 95% by mass.

Abstract: Provided are novel pyridine compounds represented by the following formula (7): wherein R1 and R4 may be the same or different and are each a linear or branched alkyl group having 1 to 4 carbon atoms; R2 and R5 are hydrogen atoms, or may be the same or different and are each a halogen atom, lower alkyl group or lower alkoxy group; R3 is a linear or branched alkyl group having 2 to 12 carbon atoms; R6 is a linear or branched alkyl group having 1 to 18 carbon atoms; and Z is a chlorine atom, bromine atom or iodine atom or an OSO2R7 group in which R7 is a lower alkyl group or a substituted or unsubstituted phenyl group. Also provided is their production process, which can easily provide them at low cost from readily-available pyridine compounds as starting raw materials.
