Reaction Steps
To a mixture of 5-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.15 g, 0.35 mmol, 1 eq), 1-(1-methyl-1H-pyrazol-3-yl)cyclopropanamine (0.058 g, 0.42 mmol, 1.2 eq), HOBT (0.08 g, 0.069 mmol, 1.7 eq), EDC.HCl (0.073 g, 0.014 mmol, 1.8 eq), in DCM at ambient temperature under nitrogen was added Diisopropylehtylamine (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 is 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 the final purification was done by preparative HPLC. Yield: 0.06 g (45%)1H NMR (400 MHz, DMSO-d6): δ 1.18-1.20 (m, 4H), 2.29 (s, 3H), 2.81-2.82 (d, 3H, J=4.64 Hz), 3.73 (s, 3H), 3.96 (s, 3H), 6.06-6.07 (d, 1 H, J=2.4 Hz), 7.12 (s, 1H), 7.32-7.34 (dd, 1H, J=8.4, 1.6 Hz), 7.38-7.42 (t, 2H, J=8.8 Hz), 7.48-7.49 (d, 2H, J=2.34 Hz), 7.59 (s, 1H), 7.71-7.73 (d, 1H, J=8.4 Hz), 7.97-7.97-8.01 (m, 2H), 8.47-8.48 (d, 1H, J=4.8 Hz), 8.69 (s, 1H). LCMS: (ES+) m/z=553.2 (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
