Procedure
In analogy to the procedure described in example 14 b], (2S)-2-ethoxy-3-(2-fluoro-4-hydroxy-phenyl)-propionic acid methyl ester was reacted with 4-chloromethyl-2-(4-chloro-phenyl)-thiazole (example 14 a]) in the presence of cesium carbonate and potassium iodide to yield (S)-3-{4-[2-(4-chloro-phenyl)-thiazol-4-ylmethoxy]-2-fluoro-phenyl}-2-ethoxy-propionic acid methyl ester as light yellow oil.
