Procedure

To (2′-ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid methyl ester (0.091 g, 0.24 mmol) and triethylamine (0.05 mL, 0.36 mmol) in CH2Cl2 (1 mL) was added methyl chloroformate (0.03 mL, 0.36 mmol), and the mixture was stirred at room temperature for 20 minutes. Once no starting material was seen by analytical LCMS, the reaction was quenched with H2O and diluted with CH2Cl2 and saturated aqueous NaHCO3. The aqueous layer was separated and extracted with CH2Cl2, and the combined organic layers were dried over MgSO4, filtered, and concentrated, and the residue was purified by silica gel chromatography (0-100% EtOAc in hexanes) to give the title compound.
