Procedure

In analogy to the procedure described in example 14 b], [rac]-2-ethoxy-3-(4-hydroxy-2-methyl-phenyl)-propionic acid ethyl ester (example 10 b]) was reacted with 4-bromomethyl-5-methyl-2-phenyl-thiazole [PCT Int. Appl. (2001), WO 01/9805 A1] in the presence of cesium carbonate and potassium iodide to yield [rac]-2-ethoxy-3-[2-methyl-4-(5-methyl-2-phenyl-thiazol-4-ylmethoxy)-phenyl]-propionic acid ethyl ester as colorless liquid.
