Reaction Steps

{5-Chloro-2′-[(cyclopropanecarbonyl-ethyl-amino)-methyl]-4′-fluoro-biphenyl-3-yl}-acetic acid ethyl ester (0.118 g, 0.28 mmol) and sodium thiomethoxide (0.043 g, 0.62 mmol) were combined in DMF (2 mL) and stirred at 100° C. overnight. Analytical LCMS indicated that the fluoride hadn't been displaced, but the ethyl ester had hydrolyzed. Additional sodium thiomethoxide (0.040 g, 0.57 mmol) was added, and the reaction was stirred overnight at 100° C. Analytical LCMS indicated that the reaction was complete, so the mixture was acidified with 1N aqueous HCl (4 mL) and worked-up with EtOAc and H2O. The combined organic layers were dried, filtered, and concentrated, and the residue was purified by preparative HPLC to give the title compound. M+H is 418.
