Procedure

To a mixture of 3-(4-fluoro-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.04 g, 0.095 mmol, 1 eq), 1-(pyrazin-2-yl)cyclopropanamine (0.015 g, 0.011 mmol, 1.2 eq) and Py-Bop (0.064 g, 0.12 mmol, 1.3 eq) in DMF at ambient temperature under nitrogen was added triethylamine (0.029 g, 0.28 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: 0.034 g (66%). 1H NMR (400 MHz, CD3OD): δ 8.60 (d, J=1.6 Hz, 1H), 8.52 (m, 1H), 8.37 (d, J=2.4 Hz, 1H), 7.98-7.95 (m, 2H), 7.92 (dd, J=1.6, 7.8 Hz, 1H), 7.85 (d, J=1.6 Hz, 1H), 7.55 (d, J=8.4 Hz, 1H), 7.51 (d, J=8.0 Hz, 1H), 7.36-7.28 (m, 3H), 2.96 (s, 3H), 2.30 (s, 3H), 1.73-1.71 (m, 2H), 1.47-1.43 (m, 2H). 19F NMR (376.57 MHz, CD3OD) δ−77.68 (TFA), −112.27, −122.72 LCMS: (ES+) m/z=539.2 (M+H)+
