1.8 g 2-Chloro-4-[4-hydroxymethyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-benzonitrile were suspended in 50 ml dichloromethane and cooled in an ice bath. 0.39 ml methanesulfonylchloride and 0.89 ml triethylamine were added. The resulting mixture was stirred at 0° C. for one hour then washed with water and brine, dried over MgSO4. The solvent was removed in vacuo to obtain 1.0 g methanesulfonic acid 5-(3-chloro-4-cyano-phenoxymethyl)-2-(4-trifluoromethyl-phenyl)-thiazol-4-ylmethyl ester as pale yellow solid.
