Versuchsvorschrift
{2-[3-(3-Methoxy-phenoxy)-5-(S)-2-methoxy-1-methyl-ethoxy)-benzoylamino]-thiazol-4-yl}acetic acid ethyl ester was prepared from 3-{(1S)-2-methoxy-(methylethyl)oxy}-5-{[3-methoxy-phenyl]oxy}benzoic acid (prepared in analogy to the method described in general synthetic descriptions F, using 3-methoxyphenylboronic acid in step D)) and ethyl 2-aminothiazol-4-ylacetate following synthetic description A.
