Procedure
To an iced cooled solution of 1.1 g 2-[4-Butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-ethanol dissolved in 50 ml dichloromethane were added 0.56 g commercially available 2-Chloro-4-hydroxybenzonitrile and 0.95 g triphenylphosphine. To this solution was added dropwise 0.57 ml Diethylazodicarboxylate. The cooling bath was removed and reaction mixture stirred at room temperature for six hours. The solvent was removed in vacuo and the residue purified by RP-HPLC to provide 400 mg 4-{2-[4-Butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-ethoxy}-2-chloro-benzonitrile as lyophilisate.
