Abstract
1-methyl-pyrazole-3-carboxylic acid was synthesized using 3-methylpyrazole as raw material by twostep reaction of oxidation and methylation in 32.2% total yield.The effects of reaction time,reaction temperature and ratio of materials were investigated and optimized.The structure of target compound was confirmed by IR spectrum and liquid chromatography.
