Process for preparing N-substituted 1H-pyrazole-5-carboxylate compounds and derivatives thereof |
| abstract |
The present invention relates to a process for preparing an N-substituted 1H-pyrazole-5-carboxylate compound of the formula (I-A) n ncomprising the steps ofn i) deprotonating a compound of the formula (II) nn n n n n n n n n n n n in which the variables R 1 , R 2 and r are each as defined in the description and the claims, n with a magnesium-organic base having a carbon bound magnesium; and n n n ii) subjecting the product obtained in step (i) to a carbonylation by reacting it with a reagent selected from the group consisting carbon dioxide or a carbon dioxide equivalent, to obtain a compound of formula (I-A);n nand it relates to further conversions to yield a N-substituted 1H-pyrazole-5-carbonyl chloride compound of the formula (I) |
