실험 절차

[2′-(3-Benzyl-1-ethyl-ureidomethyl)-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl]-acetic acid ethyl ester (46.57 g) in THF (470 mL) and ethanol (370 mL) was treated with 1N aqueous NaOH (2 mL) for 45 minutes at room temperature. The mixture was acidified with 1N aqueous HCl (270 mL) and extracted three times with dichloromethane, the organics were dried with magnesium sulfate, filtered and concentrated, and the residue was purified by preparative HPLC to give [2′-(3-benzyl-1-ethyl-ureidomethyl)-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl]-acetic acid.
