Reaction Steps

3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.2 g, 0.5 mmol, 1 eq), 1-(4-methyloxazol-5-yl)cyclopropanamine (0.103 g, 0.74 mmol, 1.2 eq), EDCI.HCl (0.105 g, 0.54 mmol, 1.1 eq), HOBT (0.067 g, 0.5 mmol, 1.0 eq) and TEA (0.21 ml, 1.5 mmol, 3 eq) were dissolved in dichloromethane and the above mixture was stirred at room temperature for 18 h. The mixture was then added with water. The organic layer was separated, washed with water and concentrated to give the crude product which was purified by Prep. HPLC. Yield: 25 mg (25%) 1H NMR (400 MHz, DMSO-d6): δ 1.21 (broad s, 4H), 2.17 (s, 3H), 2.28 (s, 3H), 2.83 (d, J=4.8 Hz, 3H), 7.37-7.43 (m, 4H), 7.56 (d, J=1.6 Hz, 1H), 7.74-7.79 (m, 3H), 7.98-8.02 (m, 2H), 8.0 (s, 1H), 8.44-8.45 (m, 1H), 9.20 (s, 1H). LCMS: (ES+) m/z=524.2 (M+H)+
