反応手順
In analogy to the procedure described in example 17 a], [rac]-3-(3-allyl-4-hydroxy-naphthalen-1-yl)-2-ethoxy-propionic acid ethyl ester was reacted with 2-(5-methyl-2-phenyl-oxazole-4yl)-ethanol in tetrahydrofuran in the presence of triphenylphosphine and DBAD (di-tert-butyl azodicarboxylate) to yield [rac]-3-{3-allyl-4-[2-(5-methyl-2-phenyl-oxazol-4-yl)-ethoxy]-naphthalen-1-yl}-2-ethoxy-propionic acid ethyl ester, which was further saponified in analogy to the procedure described in example 91 e] to yield [rac]-3-{3-allyl-4-[2-(5-methyl-2-phenyl-oxazol-4-yl)-ethoxy]-naphthalen-1-yl}-2-ethoxy-propionic acid as colorless solid.
