The reaction mixture was diluted by addition of 50 ml ethyl acetate, washed with one molar hydrochloric acid then dried over MgSO4. The solvent was removed in vacuo and the residue purified by RP-HPLC to provide 30 mg of 2-chloro-4-[4-methoxymethyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-benzonitrile as lyophilisate.
