The present invention is directed to a process for the enantioselective hydrolysis of an ester of formula (I), which comprises reacting a mixture of C4-enantiomers of esters of formula (I), or salts thereof, with an esterase enzyme in the presence of a solvent. The invention is further directed to the transformation of said esters of formula (I) into enantiomerically enriched pyrazoles.
