Procedure

A solution of the ethyl ({4-[(2-(ethyloxy)-1-{6-[4-(trifluoromethyl)phenyl]-2-pyridinyl}ethyl)thio]-2-methylphenyl}oxy)acetate (Enantiomer 1) (12 mg, 0.023 mmol) in THF (1 mL) and MeOH (1 mL) was treated with aqueous NaOH (2N, 1 mL) and the resulting mixture agitated at ambient temperature for 15 h. Aqueous HCl (2N, 1 mL) was then added and the organic solvents removed under vacuum using a Genevac. The residue was the then made up to 2 mL by the addition of water and then extracted using DCM (3×3 mL) in an hydrophobic frit. The residue was reduced and then purified further by mass directed autoprep HPLC to afford the title compound as an oil (7 mg).
