Procedure

To a mixture of 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.04 g, 0.099 mmol, 1 eq), 1-(pyridazin-3-yl)cyclopropanamine HCl salt (0.018, 0.099 mmol, 1 eq) and Py-Bop (0.067 g, 0.13 mmol, 1.3 eq) in DMF at ambient temperature under nitrogen was added triethylamine (0.026 g, 0.3 mmol, 3 eq). The clear mixture was stirred at ambient temperature for 12 h. The mixture was concentrated, diluted with water and extracted with EtOAc. The organic layer was further washed with water, dried over sodium sulphate and concentrated. The product obtained was purified by preparative HPLC. Yield: 0.031 mg (60%). 1H NMR (400 MHz, CDCl3): δ 9.17 (s, 1H), 7.92-7.96 (m, 3H), 7.77-7.69 (m, 4H), 7.65 (s, 1H), 7.56 (d, J=8.4 Hz, 1H), 7.38 (d, J=8.0 Hz, 1H), 7.30 (dd, J=1.6, 8.4 Hz, 1H), 7.23-7.19 (m, 2H), 5.94 (bs, 1H), 3.0 (s, 3H), 2.33 (s, 3H), 1.89-1.86 (m, 2H), 1.60-1.57 (m, 2H). 19F NMR (376.47 MHz, CDCl3): δ −75.82 (TFA), −109.29 LCMS: (ES+) m/z=521.0 (M+H)+
