Procedure
3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-4-methylbenzoic acid (0.2 g, 0.5 mmol, 1 eq), 1-(5-methylthiazol-2-yl)cyclopropanamine (0.093 g, 0.6 mmol, 1.2 eq), EDCI.HCl (0.103 g, 0.54 mmol, 1.1 eq), HOBT (0.067 g, 0.5 mmol, 1.5 eq) and TEA (0.21 ml, 1.5 mmol, 3 eq) were dissolved in dichloromethane and the mixture was stirred at room temperature for 18 h. The mixture was then added with water, and the organic layer was separated and washed with water, and the product was purified by preparative TLC. Yield: 25 mg (15%). 1HNMR (400 MHz, DMSO-d6): δ1.34-1.37 (m, 2H), 1.50-1.53 (m, 2H), 2.31 (s, 3H), 2.35 (s, 3H), 2.83-2.84 (d, J=4.8 Hz, 3H), 7.27 (d, J=1.2 Hz, 1H), 7.39-7.47 (m, 4H), 7.60 (d, J=1.6 Hz, 1H), 7.76-7.78 (d, J=8.4 Hz 1H), 7.83-7.85 (m, 2H), 8.02 (m, 2H), 8.45 (m, 1H), 9.51 (s, 1H) LCMS: (ES+) m/z=540 (M+H)+
