0.070 g (0.140 mmol) of the above prepared 2-methyl-2-(2-methyl-4-{2-[2-methyl-6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-ethoxy}-phenoxy)-propionic acid ethyl ester was dissolved in 0.84 ml of THF/EtOH=1/1, treated with 0.42 ml (3 eq.) of 1N NaOH and kept at ambient temperature for 4 h. The reaction mixture was then poured onto crashed ice/AcOEt/HCl dil., the aqueous phase extracted again with AcOEt; the combined organic layers were washed with water, dried over sodium sulfate, and evaporated to dryness to yield 0.057 g of the title product as light yellow foam.
