Procedure

To a mixture of 5-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.2 g, 0.46 mmol, 1 eq), 1-(pyrimidin-2-yl)cyclopropanamine (0.074 g, 0.55 mmol, 1.2 eq), HOBT (0.105 g, 0.77 mmol, 1.7 eq), EDC.HCl (0.0.158 g, 0.82 mmol, 1.8 eq), in DCM at ambient temperature and under nitrogen atmosphere was added diisopropylethylamine (0.297 g, 2.2 mmol, 5.0 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 further purified by column chromatography (neutral alumina) using 0.5% Methanol/DCM and preparative HPLC. Yield: 0.055 g (45%). 1H NMR (400 MHz, DMSO-d6): δ 1.43-1.44 (m, 2H), 1.59-1.62 (m, 2H), 2.31 (s, 3H), 2.81-2.82 (d, 3H, J=4.56 Hz), 4.01 (s, 3H), 7.17 (s, 1H), 7.26-7.29 (t, 1H, J=4.8 Hz), 7.33-7.36 (dd, 1H, J=8.4, 4 Hz), 7.38-7.43 (t, 2H, J=8.8 Hz), 7.50-7.51 (d, 1H, J=1.6 Hz), 7.72-7.76 (m, 2H), 7.97-8.01 (m, 2H), 8.48-8.49 (d, 1H, J=4.4 Hz), 8.7 (d, 2H, J=4.8 Hz), 8.87 (s, 1H). LCMS: (ES+) m/z=551.2 (M+H) Column-Ascentis Express C18 (5×2.1 mm-2.7 μm) Mphase A: 2% MeCN-98% H2O-10 mM NH4COOH Mphase B: 98% MeCN-2% H2O-10 mM NH4COOH Flow: 1 mL/Min
