Versuchsvorschrift
In analogy to the procedure described for example 1 f], {6-[4-bromo-2-methyl-5-(4-trifluoromethyl-phenyl)-2H-pyrazol-3-ylmethoxy]-indol-1-yl}-acetic acid ethyl ester was treated with LiOH to obtain {6-[4-bromo-2-methyl-5-(4-trifluoromethyl-phenyl)-2H-pyrazol-3-ylmethoxy]-indol-1-yl}-acetic acid as colorless crystals.
