were studied as potential falcipaininhibitors and therefore potential antiparasitic lead compounds, with the 5-substituted-2-cyanopyrimidine chemical class emerging as the most potent and promising leadseries. Through a sequential leadoptimization process considering the different positions present in the initial scaffold, nanomolar and subnanomolar inhibitors at falcipains 2 and 3 were identified

The present invention relates to a novel process for the preparation of a pyrazole carboxylic acid derivative of the formula (I) wherein R1 is C1-7-alkyl and R3 is C1-7-alkyl which is optionally substituted with halogen or C1-4-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 (Int. Patent Publication WO 2011/117264). A synthetic approach to the pyrazole carboxylic acid derivative of the formula I has been described in scheme 3 of the Int. Patent Publication WO 2011/117264 applying a method disclosed in Hanzlowsky et al, J. Heterocyclic Chem. 2003, 40(3), 487-489. However, under the acid-catalyzed cyclocondensation conditions described, besides of the desired isomer, also a substantial amount of the undesired N-1 substituted isomer was formed. In many cases, especially on larger scale, this undesired isomer is the major product in the reaction mixture with ratios of up to 70:30 in favor of the undesired isomer, leading to isolated yields of ca. 30% of the undesired isomer, along with ca. 25% of the desired isomer.
