Procedure

To (2′-ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid ethyl ester (0.59 g, 1.49 mmol) and diisopropylethylamine (0.65 mL, 3.73 mmol) in CH2Cl2 (6 mL) at 0° C. was added phosgene (20% in toluene; 1.2 mL, 2.24 mmol), and the reaction was stirred for 1 hour. 4-Hydroxybenzylamine (0.278 g, 2.24 mmol) and triethylamine (1 mL, 7.47 mmol) were then added, and the reaction was stirred for 2 hours. Analytical LCMS indicated the starting material was still present, so additional 4-hydroxybenzylamine (0.184 g, 1.49 mmol) was added, and the reaction was stirred for another 30 minutes. The mixture was partitioned between CH2Cl2 and H2O, and the organic layer was dried over MgSO4, filtered, and concentrated. The residue was purified by silica gel chromatography (0-100% EtOAc in hexanes) to give the title compound.
