Procedure

To {2′-[3-(4-chloro-benzyl)-1-ethyl-ureidomethyl]-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl}-acetic acid ethyl ester (0.196 g, 0.35 mmol) in THF (2 mL) and MeOH (2 mL) was added 1N aqueous LiOH (2 mL), and the reaction was stirred at room temperature for 2 hours. The mixture was acidified with 1N aqueous HCl and extracted three times with EtOAc, and the combined organic layers were dried and concentrated. The residue was purified by preparative HPLC to give the title compound.
