Reaction Steps

5-(2-(4-Fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.2 g, 1 eq), 1-(1-methyl-1H-imidazol-4-yl)cyclopropanamine (0.07 g, 1.1 eq), EDCI.HCl (0.13 g, 1.5 eq), HOBT (0.094 g, 1.5 eq) and TEA (0.19 ml, 3 eq) were dissolved in dichloromethane and the above solution was stirred at room temperature for 18 h. Later water was added and organic layer was separated. The organic layer was washed with water and the crude product was purified by Prep. HPLC. Yield: 24.69 mg (10%) 1HNMR (400 MHz, CDCl3): δ 1.39 (s, 4H), 2.30 (s, 3H), 2.99-3.01 (d, J=4.6 Hz, 3H), 3.81 (s, 3H), 4.04 (s, 3H), 5.90 (s, 1H), 6.87 (s, 1H), 7.16-7.25 (m, 3H), 7.24 (s, 1H), 7.51 (d, J=8.4 Hz, 1H), 7.65 (s, 1H), 7.98-7.99 (m, 3H), 8.29 (s, 1H), 8.95 (s, 1H). LCMS: (ES+) m/z=553.2 (M+H). Method: Column-Ascentis Express C18 (5×2.1 mm-2.7 μm) Mphase A: 2% ACN-98% H2O-10 mM NH4COOH Mphase B: 98% ACN-2% H2O-10 mM NH4COOH Flow: 1 ML/Min
