Participants

Reaction Steps

To a solution of (2′-ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid methyl ester (0.207 g, 0.54 mmol) and diisopropylethylamine (0.38 mL, 2.16 mmol) in CH2Cl2 (2 mL) at 0° C. was added phosgene (20% in toluene; 0.43 mL, 0.81 mmol), and the reaction was stirred for 2 hours. Pyrrolidine (0.13 mL, 1.62 mmol) was added, and the reaction was stirred at 0° C. for 30 minutes. The mixture was concentrated, and the residue was purified by silica gel chromatography (20-40% EtOAc in hexanes) to give the title compound.
