実験手順

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