In analogy to the procedure described for example 3 c], (6-hydroxy-indol-1-yl)-acetic acid ethyl ester (example 2 e]) was reacted with [5-(4-fluoro-3-trifluoromethyl-phenyl)-2-methyl-2H-pyrazol-3-yl]-methanol in the presence of N,N,N′,N′-tetramethyl azodicarboxamide and tributylphosphine to give {6-[5-(4-fluoro-3-trifluoromethyl-phenyl)-2-methyl-2H-pyrazol-3-ylmethoxy]-indol-1-yl}-acetic acid ethyl ester as white solid.
