10% Palladium on carbon (50 mg, 10 wt %) was added to a solution of 2-(3-{1-[(4-isopropyl-phenyl)-acetyl]-piperidin-3-yl}-phenoxy)-2-methyl-propionic acid benzyl ester (494 mg, 0.96 mmol) in methanol (15 mL) and the resulting mixture hydrogenated at atmospheric pressure for 3 h. The reaction mixture was filtered through a plug of celite and the celite plug washed thoroughly with ethyl acetate. The combined filtrates were concentrated under reduced pressure to provide 319 mg (78%) of 2-(3-{1-[(4-Isopropyl-phenyl)-acetyl]-piperidin-3-yl}-phenoxy)-2-methyl-propionic acid as a clear oil.
