반응 단계
In analogy to the procedure described in example 1 d], [rac]-2-ethoxy-3-(3-fluoro-4-hydroxy-phenyl)-propionic acid ethyl ester (example 7 a]) was reacted with (4-methyl-2-phenyl-thiazol-5-yl)-methanol in tetrahydrofuran in the presence of triphenylphosphine and DEAD (diethyl azodicarboxylate) to yield [rac]-2-ethoxy-3-[3-fluoro-4-(4-methyl-2-phenyl-thiazol-5-ylmethoxy)-phenyl]-propionic acid ethyl ester, which was further saponified in analogy to the procedure described in example 4 e], to yield [rac]-2-ethoxy-3-[3-fluoro-4-(4-methyl-2-phenyl-thiazol-5-ylmethoxy)-phenyl]-propionic acid as a light yellow solid.
