実験手順

0.143 g (0.28 mmol) of the above prepared [rac]-(2-methyl-4-{1-[2-methyl-6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-ethoxy}-phenylsulfanyl)-acetic acid tert-butyl ester was dissolved in 2.75 ml of THF/EtOH=1/1, treated with 1.38 ml (3 eq.) of 1N NaOH and kept at ambient temperature for 5 h. The reaction mixture was then poured onto crashed ice/AcOEt/HCl dil., the organic layer was washed with water, dried over sodium sulfate, and evaporated to dryness to leave, since recrystallisation from AcOEt/hexane failed, 0.095 g of the title compound as colorless foam.
