| titleOfInvention | Method for producing 4-methylpyrazole-5-carboxylic acid ester |
| abstract | PROBLEM TO BE SOLVED: To provide a novel method for producing 4-methylpyrazole-5-carboxylic acid ester. [Chemical 1] (Wherein R 1 , R 2 and R 3 independently represent a C 1-4 alkyl group) are selected from formaldehyde and its equivalents in a hydrocarbon solvent in the presence of a solvent dehydrating agent. Formula (2) by reacting in the presence of one or more kinds, one or more acid catalysts selected from mineral acids and Lewis acids, and hydrogen chloride (wherein R 1 , R 2 and R 3 are And 4-chloromethylpyrazole-5-carboxylic acid ester represented by the same meaning. In addition, the 4-chloromethylpyrazole-5-carboxylic acid ester represented by the formula (2) is dechlorinated in a hydrocarbon solvent under reducing conditions, and then treated with a detoxifying agent to thereby convert bis (chloromethyl) ether. A method for producing 4-methylpyrazole-5-carboxylic acid ester represented by the formula (3), which is detoxified. [Selection figure] None |
