Procedure
In analogy to the procedure described in example 1 g], (S)-2-ethoxy-3-[2-fluoro-4-(5-methyl-2-o-tolyl-oxazol-4-ylmethoxy)-phenyl]-propionic acid methyl ester was treated with LiOH to obtain (S)-2-ethoxy-3-[2-fluoro-4-(5-methyl-2-o-tolyl-oxazol-4-ylmethoxy)-phenyl]-propionic acid as colorless liquid.
