| titleOfInvention | Method for producing 1-substituted-5-chloro-4-methylpyrazole |
| abstract | The present invention provides compounds of formula I Embedded image In the formula, R represents C 1 -C 8 -alkyl or C 5 -C 10 -cycloalkyl, and each of these groups may have one or more substituents. 1-substituted-5-chloro-4-methylpyrazole represented by the formula II Embedded image 中 In the formula, R represents the above-mentioned meaning. By reacting 1-substituted-4-methylpyrazole represented by｝ with chlorine to obtain a compound represented by formula I and a compound represented by formula III Embedded image 中 In the formula, R represents the above-mentioned meaning. A process for obtaining a mixture with a 1-substituted-3,5-dichloro-4-methylpyrazole represented by the formula: wherein the compound represented by the formula III and the compound represented by the formula I in the obtained mixture are The compound represented by the formula II is separated from the compound represented by the formula III, and the separated compound represented by the formula III is dehalogenated to obtain a compound represented by the formula II. To a step of reacting the compound with chlorine. |
