Versuchsvorschrift

To a solution of isopropyl 2-[4-fluoro-3-[[5-(3-fluorophenyl)-2,3-dimethyl-phenyl]methylamino]-2-methyl-phenoxy]acetate (80 mg, 0.17 mmol, 1.0 eq) in a mixture of THF (5 mL) and MeOH (5 mL) was added NaOH (2M aqueous solution, 5 mL, 10 mmol). The reaction was stirred for 3 h then the organic solvent was removed under reduced pressure. The remaining aqueous solution was adjusted to pH 5 with diluted HCl and the mixture extracted with EtOAc. The combined organic extracts were dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (CH2Cl2:MeOH, 400:1 to 4:1) to give the title compound as a white solid (74 mg, 97%).
