HCID 68615799(2S)-3-{2-chloro-4-[2-(4-chloro-phenyl)-thiazol-4-ylmethoxy]-phenyl}-2-ethoxy-propionic acid methyl ester

Procedure

In analogy to the procedure described in example 14 b], (2S)-3-(2-chloro-4-hydroxy-phenyl)-2-ethoxy-propionic acid methyl ester was reacted with 4-chloromethyl-2-(4-chloro-phenyl)-thiazole (example 14 a]) in the presence of cesium carbonate and potassium iodide to yield (2S)-3-{2-chloro-4-[2-(4-chloro-phenyl)-thiazol-4-ylmethoxy]-phenyl}-2-ethoxy-propionic acid methyl ester as light yellow solid.
