実験手順
In analogy to the procedure described for example 9 c], [2-(2,2,2-trifluoro-ethyl)-5-(4-trifluoromethoxy-phenyl)-2H-pyrazol-3-yl]-acetonitrile was treated with sodium hydroxide in water/ethanol 1/1 at 85° C. to give [2-(2,2,2-trifluoro-ethyl)-5-(4-trifluoromethoxy-phenyl)-2H-pyrazol-3-yl]-acetic acid as brown crystals.
