Procedure

To a mixture of 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.075 g, 0.186 mmol, 1.0 eq), 1-(pyridazin-4-yl)cyclopropanamine HCl (0.025 g, 0.185 mmol, 1.0 eq) in DMF at 0° C. was added TEA (0.094 g, 0.93 mmol, 5.0 eq) and BOP reagent (0.123 g, 0.278 mmol, 1.5 eq). The reaction mixture was stirred at RT overnight. The reaction mixture was diluted with water, extracted with EtOAc. the The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by silica gel (60-120) column chromatography using 4% MeOH/CHCl3 as eluent, and further purified the product by prep HPLC. Yield: 0.050 g (52.00%). 1H NMR (400 MHz, CD3OD): δ 9.44 (s, 1 H), 9.15 (d, 1H), 9.11 (s, 1H), 8.02-7.94 (m, 2H), 7.86 (dd, J=2.3, 4.3 Hz, 2H), 7.73 (br s, 1H), 7.68 (d, J=8.8 Hz, 1H), 7.66 (d, J=1.2 Hz, 1H), 7.48 (d, J=8.8 Hz, 1H), 7.40 (dd, J=1.8, 8.5 Hz, 1H), 7.29 (t, J=8.9 Hz, 2H), 2.96 (s, 3H), 2.37 (s, 3H), 1.71 (s, 4H). 19F NMR (376.51 MHz, CD3OD): δ −78.16 (TFA), −113.29 LCMS: (ES+) m/z=521.2 (M+H)+
