To a solution of 1-(2,4-dichloro-phenyl)-cyclopropanecarbonyl chloride (0.37 mmol) in CH2Cl2 was added triethylamine (0.16 mL, 1.12 mmol), and the mixture was stirred for 10 minutes. (2′-Ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid ethyl ester (0.146 g, 0.37 mmol) in CH2Cl2 was then added, and the reaction was stirred for 30 minutes at room temperature. Additional triethylamine (0.1 mL, 0.72 mmol) was added, and the reaction was stirred for another 30 minutes. Analytical LCMS indicated that starting material was still present, so another portion of triethylamine (0.1 mL, 0.72 mmol) was added, and the reaction was stirred for 1 hour and then worked-up with CH2Cl2 and H2O. The combined organic layers were dried and concentrated, and the residue was purified by silica gel chromatography (10-40% EtOAc in hexanes) to give the title compound.
