In analogy to the procedure described in example 10 d], 2-ethoxy-3-(2-methyl-4-{1-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-butoxy}-phenyl)-propionic acid ethyl ester (mixture of two diastereomeric racemates) was treated with LiOH to obtain 2-ethoxy-3-(2-methyl-4-{1-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-butoxy}-phenyl)-propionic acid as a mixture of two diastereomeric racemates as colorless foam.
