Process for the preparation of 1-alkyl-pyrazole-5-carboxylic acid esters |
| abstract |
1-alkyl-pyrazole-5-carboxylic acid esters are prepared by reacting the enolate of a 2,4-diketocarboxylic acid ester with an N-alkylhydrazinium salt in the presence of a solvent. This process allows a particularly economic preparation of 1-alkyl-pyrazole-5-carboxylic acid esters in a simple manner and with only little formation of undesirable isomers. |
