| titleOfInvention | Purification method of 1-methylpyrazole-4-carboxylates |
| abstract | The present invention relates to an improved process for the production of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid, which is a useful intermediate in the production of fungicides. In particular, the present invention relates to a method for processing compounds represented by structural formula III: Wherein R 1 is a C 1 -C 6 alkyl group and R 2 is CF 3 , CF 2 H or CFH 2 , the method comprises the following steps: a) contacting the compound represented by the structural formula III with a base, and b) contacting the compound represented by the structural formula III The compound is separated from the base. |
