The present invention relates to a novel process for the preparation of a pyrazole carboxylic acid derivative of the formula
wherein R
1
is C
1-7
-alkyl and R
3
is C
1-7
-alkyl which is optionally substituted with halogen or C
1-4
-alkoxy.
The pyrazole carboxylic acid derivative of the formula I can be used as building block in the preparation of pharmaceutically active principles e.g. for compounds acting as phosphodiesterase (PDE) inhibitors, particularly PDE10 inhibitors. PDE10 inhibitors have the potential to treat psychotic disorders like schizophrenia.

and A are as defined in the description and in the claims, as well as physiologically acceptable salts and esters thereof. These compounds inhibit PDE10A and can be used for the treatment of various diseases, including central nervous system disorders such as Alzheimer's disease, Parkinson's disease, and schizophrenia.
