Reaction Steps

5-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-2-methoxy-4-methylbenzoic acid (0.2 g, 1 eq), 1-(5-methylthiazol-2-yl)cyclopropanamine (0.07 g, 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. Then water was added to the mixture and the organic layer was separated. The organic layer was washed with water and the product was purified by Prep. HPLC. Yield: 65 mg (25%)1HNMR (400 MHz, CDCl3): δ 1.43-1.46 (m, 2H), 1.74-1.77 (m, 2H), 2.32 (s, 3H), 2.37 (s, 3H), 3.01-3.03 (d, J=5.2 Hz, 3H), 4.04 (s, 3H), 5.89 (m, 1H), 6.91 (s, 1H), 7.16 (t, 2H), 7.27 (m, 2H), 7.51 (d, J=4 Hz, 1H), 7.66 (s, 1H), 8.00 (m, 2H), 8.13 (s, 1H), 8.7 (s, 1H). LCMS: (ES+) m/z=570.2 (M+H).
