Product 1

HCID 22647432[Rac]-2-butoxy-3-{2-methyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-propionic acid

Procedure

In analogy to the procedure described in example 10 d], [rac]-2-butoxy-3-{2-methyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-propionic acid methyl ester was treated with 1 N LiOH to obtain [rac]-2-butoxy-3-{2-methyl-4-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-phenyl}-propionic acid as yellow solid.
