Procedure
Trans-2-[methyl-(1-{4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-piperidin-4-yl)-carbamoyl]-cyclopentanecarboxylic acid benzyl ester was hydrolyzed with lithium hydroxide in methanol and water. The resulted crude mixture was concentrated and the residue was dissolved in ethyl acetate and water with citric acid as acidifying agent. The organic layer then was concentrated and purified by reverse phase HPLC. The mixture of isomers was obtained as a yellow solid. LCMS calcd for C30H31F3N4O5 (m/e) 584, obsd 585 (M+H).
