Versuchsvorschrift

A 2 N sodium hydroxide aqueous solution (0.23 mL) was added to a solution of [5-(4-{1-ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butoxy)-3-methyl-phenyl]-propyl}-2-methyl-phenyl)-pyridin-3-yl]-acetic acid methyl ester (Example 102-(1); 39.5 mg, 0.0762 mmol) in methanol (1.3 mL), and the mixture was stirred for two hours. A saturated aqueous ammonium chloride solution was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by thin layer silica gel chromatography (8% methanol/dichloromethane) to give the title compound (21.6 mg, 56%).
