Procedure

To a mixture of 5-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.080 g, 0.185 mmol, 1.0 eq), 1-(pyrimidin-4-yl)cyclopropanamine HCl (0.025 g, 0.185 mmol, 1.0 eq) in DMF and at 0° C. was added TEA (0.094 g, 0.930 mmol, 5.0 eq) and BOP reagent (0.120 g, 0.271 mmol, 1.5 eq). The reaction mixture was warmed to RT, and stirring was continued at RT overnight. The reaction mixture was diluted with water and extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by prep HPLC. Yield: 0.058 g (58.0%). 1H NMR (400 MHz, CD3OD): δ 9.03 (s, 1H), 8.64 (d, J=1.4 Hz, 1H), 7.97-7.79 (m., 2H), 7.76 (s, 1H), 7.65 (d, J=5.6 Hz, 1H), 7.52 (d, J=8.4 Hz, 1H), 7.31-7.25 (m, 3H), 7.19 (s, 1H), 4.09 (s, 3H), 2.95 (s, 3H), 2.30 (s, 3H), 1.88-1.85 (m, 2H), 1.55-1.52 (m, 2H). 19F NMR (376.57 MHz, CD3OD): δ−77.58 (TFA), −112.32, −122.76. LCMS: (ES+) m/z=569.2 (M+H)+
