실험 절차

In analogy to the procedure described in example 14 b], [rac]-2-(4-hydroxy-2-methyl-benzyl)-butyric acid ethyl ester 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 [rac]-2-{2-methyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-benzyl}-butyric acid ethyl ester as colorless oil.
