Participants

Reaction Steps

To a mixture of 5-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.04 g, 0.092 mmol, 1 eq), 1-(pyridazin-3-yl)cyclopropanamine HCl salt (0.017 g, 0.092 mmol, 1 eq) and Py-Bop (0.062 g, 0.12 mmol, 1.3 eq) in DMF at ambient temperature under nitrogen was added triethylamine (0.028 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 flash column chromatography using 4% MeOH/CHCl3 as eluant. Yield: 0.032 g (63%). 1H NMR (400 MHz, CD3OD): δ 9.15 (s, 1H), 9.00 (d, J=3.8 Hz, 1H), 8.53-8.40 (m, 1H), 8.02-7.95 (m, 2H), 7.84 (dd, J=1.5, 8.5 Hz, 1H), 7.79 (s, 1H), 7.70-7.62 (m, 2H), 7.59 (d, J=1.5 Hz, 1H), 7.34 (dd, J=1.8, 8.5 Hz, 1H), 7.31-7.26 (m, 2H), 7.16 (s, 1H), 4.09 (s, 3H), 2.98-2.95 (m, 3H), 2.38 (s, 3H), 1.89-1.87 (m, 2H), 1.57-1.52 (m, 2H). 19F NMR (376.57 MHz, CD3OD): δ −112.66 LCMS: (ES+) m/z=551.2 (M+H)+
