To {2′-[(cyclopropanecarbonyl-ethyl-amino)-methyl]-4′-fluoro-6-methoxy-biphenyl-3-yl}-acetic acid ethyl ester 0.186 g, 0.45 mmol) in DMF (0.5 mL) was added sodium thiomethoxide (0.035 g, 0.50 mmol), and the reaction was stirred at 85° C. for 2 hours. Analytical LCMS indicated that starting material was still present, so additional sodium thiomethoxide (0.070 g, 1.0 mmol) was added, and the reaction was stirred at 85° C. for another 2 hours. Analytical LCMS showed that no starting material remained, and that the ethyl ester had been hydrolyzed, so an aqueous work-up was performed, and the residue was purified by preparative HPLC to give the title compound. M+H is 414.
