HCID 22647513[Rac]-2-ethoxy-3-(4-{2-[2-(4-isopropyl-phenyl)-thiazol-4-yl]-ethoxy}-2-methyl-phenyl)-propionic acid

Procedure

In analogy to the procedure described in example 10 d], [rac]-2-ethoxy-3-(4-{2-[2-(4-isopropyl-phenyl)-thiazol-4-yl]-ethoxy}-2-methyl-phenyl)-propionic acid ethyl ester was treated with LiOH to obtain [rac]-2-ethoxy-3-(4-{2-[2-(4-isopropyl-phenyl)-thiazol-4-yl]-ethoxy}-2-methyl-phenyl)-propionic acid as colorless liquid.
