Procedure

In analogy to the procedure described in example 10 c], [rac]-2-ethoxy-3-(4-hydroxy-2-methyl-phenyl)-propionic acid ethyl ester (example 10 b]) was reacted with [rac]-cyclopropyl-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-methanol in the presence of tributylphosphine and N,N,N′,N′-tetramethyl azodicarboxamide to yield 3-(4-{cyclopropyl-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-methoxy}-2-methyl-phenyl)-2-ethoxy-propionic acid ethyl ester as a mixture of two diastereomeric racemates as yellow liquid.
