A mixture of 2-[5-(3-isopropyl-phenoxy)-4′-trifluoromethyl-biphenyl-3-yl]-4-methyl-pentanoic acid methyl ester (33 mg, 0.07 mmol), THF (0.6 mL), 10% aq. LiOH (0.2 mL) and MeOH (0.6 mL) was stirred at 30° C. for 3 h. The solution was concentrated and the residue was diluted with H2O (1 mL) and then acidified with conc HCl. The aqueous solution was extracted with DCM (3×1 mL) and the organic layers were filtered through PTFE filter. The solution was concentrated in vacuo to give a solid residue. The solid was purified using reverse phase preparative HPLC (MeCN, H2O) to afford the title compound (21.6 mg, 67%).
