実験手順

To an ice cold solution of (6-hydroxy-indol-1-yl)-acetic acid ethyl ester (35 mg, 160 μmol; example 2 e]), [2-methyl-5-(4-trifluoromethyl-phenyl)-2H-pyrazol-3-yl]-methanol (41 mg, 160 μmol) and tributylphosphine (50 μl, 19 μmol) in tetrahydrofuran (3.5 ml) was added N,N,N′,N′-tetramethyl azodicarboxamide (33 mg, 19 μmol). The cooling bath was removed and stirring continued for 14 h. The mixture was filtered over celite and the solvent removed under reduced pressure to give a brown oil which was purified by column chromatography (silica gel, heptane/AcOEt) to obtain 22 mg (50 μmol, 30%) of the title compound as colorless oil.
