Preparation method for polyfluoromethylpyrazole compound, and intermediate of compound and preparation method thereof

The invention discloses a preparation method for a polyfluoromethylpyrazole compound, and an intermediate of the compound and a preparation method thereof. The invention provides a preparation method for a compound 1 as defined in the specification. The preparation method comprises a step of subjecting a compound 2 as defined in the specification and methylhydrazine to a ring-closure reaction in an organic solvent so as to obtain the compound 1, wherein R is a C1-4 alkyl group, R is a methyl or ethyl group and x is 2 or 3. The preparation method provided by the invention uses cheap and easily available raw materials and is mild in reaction conditions, safe to operate, environment friendly, low in production cost, high in reaction conversion rate, low in the content of isomer in by-products, high in reaction yield and product purity and suitable for industrial production.

Method of manufacturing pyrazolecarboxylic compd.

PROBLEM TO BE SOLVED: To provide 1,3-disubstituted pyrazole-4-carboxylic acid obtained by reducing the content of isomers from 1,3-disubstituted pyrazole-4-carboxylic acid containing 1,5-disubstituted pyrazole-4-carboxylic acid (the isomer). SOLUTION: The production method of 1,3-disubstituted pyrazole-4-carboxylic acid comprises: preparing an aqueous solution including 1,3-disubstituted pyrazole-4-carboxylate, 1,5-disubstituted pyrazole-4-carboxylate and an organic solvent; and making the pH of this aqueous solution to the pH range where the 1,3-disubstituted pyrazole-4-carboxylic acid precipitates.
