Procedure

(2′-Ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid methyl ester (0.130 g, 0.34 mmol), N-ethyl-N-benzylcarbamoyl chloride (0.081 g, 0.41 mmol), 4-dimethylaminopyridine (0.010 g, 0.08 mmol), and triethylamine (0.12 mL, 0.85 mmol) were combined in CH2Cl2 (5 mL) and stirred at reflux overnight. The mixture was purified by silica gel chromatography (0-100% EtOAc in hexanes) to give [2′-(3-Benzyl-1,3-diethyl-ureidomethyl)-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl]-acetic acid methyl ester. The ethyl ester was then hydrolyzed with 1N aqueous LiOH in THF at room temperature to give the title compound.
