In analogy to the procedures described in example 26B] and 26C], 2-methyl-2-(3-methylamino-phenoxy)-propionic acid ethyl ester (example 26 A]) was reacted with [4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-yl]-acetic acid (prepared starting from 3-oxo-heptanoic acid ethyl ester in analogy to the sequences described in examples 27C] to 27F] and examples 26D] and 26E]) to give 2-[3-({2-[4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-yl]-acetyl}-methyl-amino)-phenoxy]-2-methyl-propionic acid ethyl ester, which was subsequently saponified to yield the title compound as light yellow amorphous solid.
