Procedure
To 0.123 g (0.516 mmol) of 2-(4-hydroxy-2-methyl-phenoxy)-2-methyl-propionic acid ethyl ester (described in WO 02/092590) and 0.163 g (0.540 mmol) of the above prepared 3-chloromethyl-2-methyl-6-(4-trifluoromethoxy-phenyl)-pyridine, dissolved in 4.7 ml of abs. acetonitrile, was added 0.184 g of Cs2CO3 (0.565 mmol). The reaction was stirred over night at ambient temperature. Pouring onto crashed ice/NH4Cl-solution, twofold extraction with AcOEt, washing with water, drying over sodium sulfate, and evaporation of the solvents, followed by flash chromatography (SiO2, hexane/AcOEt=8/2) yielded 0.243 g of pure title compound as colorless oil.
