Procedure
To (2′-ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid ethyl ester (0.196 g, 0.50 mmol) in CH2Cl2 (2 mL) at 0° C. was added diisopropylethylamine (0.21 mL, 1.24 mmol), followed by phosgene (20% in toluene, 0.39 mL, 0.75 mmol), and the mixture was stirred for 3 hours. 4-Chlorobenzylamine (0.09 mL, 0.75 mmol) was added, followed by triethylamine (0.14 mL, 1.0 mmol), and the reaction was stirred at room temperature for 20 minutes. Additional triethylamine (0.07 mL, 0.5 mmol) was added, and the reaction was stirred for 1 hour and then worked-up with CH2Cl2 and H2O. The organic layer was dried and concentrated, and the residue was purified by silica gel chromatography (0-50% EtOAc in hexanes) to give the title compound.
