Procedure

{2′-[(Cyclopropanecarbonyl-ethyl-amino)-methyl]-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl}-acetic acid ethyl ester (0.408 g, 0.88 mmol) was dissolved in THF (4 mL) and cooled to −78° C. Sodium bis(trimethylsilyl)amide (1M in THF; 1.06 mL, 1.06 mmol) was added, followed by iodomethane (0.06 mL, 0.97 mmol), and the reaction was stirred at −78° C. for 30 minutes. The mixture was quenched with saturated aqueous NH4Cl and warmed to room temperature. The mixture was extracted three times with EtOAc, and the combined organic layers were dried, concentrated, and purified by silica gel chromatography (10-40% EtOAc in hexanes) to give the title compound.
