Procedure

A suspension of 3-ethyl-1H-indol-5-ol (235 mg, 1.46 mmol), 5-chloromethyl-4-methyl-2-(4-trifluoromethyl-phenyl)-thiazole [425 mg, 1.46 mmol; PCT Int. Appl. (2002), WO 0292590 A1] and cesium carbonate (712 mg, 2.19 mmol) in DMF (3 ml) was stirred for 1.5 h at ambient temperature. Diethyl ether was added and the mixture was washed with 1N HCl and water. The organic layer was dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by column chromatography (silica gel, ethyl acetate/heptane 1:3) to give 522 mg (1.34 mmol, 86%) 5-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-1H-indole.
