実験手順
To the solution of (1S,2S)-2-(4-{3-fluoro-4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-piperazine-1-carbonyl)-cyclopentanecarboxylic acid benzyl ester in methanol, lithium hydroxide and water were added. The so formed mixture was stirred at 25° C. overnight. Solvent was removed and the residue was resuspended in ethyl acetate and water. Citric acid was added to acidify the mixture. Organic layer was concentrated and the residue was purified on a reverse phase HPLC system to give (1S,2S)-2-(4-{3-fluoro-4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-piperazine-1-carbonyl)-cyclopentanecarboxylic acid as a white solid. LCMS calcd for C28H26F4N4O5 (m/e) 574, obsd 575 (M+H).
