| description | The present invention relates to improvements in processes towards the production 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid, which is a useful intermediate in fungicide production. In particular, the invention relates to a process for treating a compound of formula III wherein R1 is C1-C6 alkyl and R2 is CF3, CF2H or CFH2, comprising the steps of (a) contacting a compound of formula III with base, and (b) separating the compound of formula III and the base. |
