Product 1

HCID 68616598(S)-3-{2,6-dimethyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-2-ethoxy-propionic acid methyl ester

Procedure

In analogy to the procedure described in example 14 b], (2S)-2-ethoxy-3-(4-hydroxy-2,6-dimethyl-phenyl)-propionic acid methyl ester (example 103 e]) was reacted with 5-chloromethyl-4-methyl-2-(4-trifluoromethyl-phenyl)-thiazole [PCT Int. Appl. (2002), WO 0292590 A1] in the presence of cesium carbonate and potassium iodide to yield (S)-3-{2,6-dimethyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-2-ethoxy-propionic acid methyl ester as yellow oil.
