To a mixture of 5-(2-(4-fluorophenyl)-3-(1H-imidazol-2-yl)-6-nitrobenzofuran-5-yl)-2-methoxybenzoic acid (300 mg, 0.634 mmol) and 1-(pyrimidin-2-yl)cyclopropanamine hydrochloride (131 mg, 0.760 mmol) in DMF (15 mL) at room temperature under a nitrogen atmosphere was added triethylamine (TEA) (0.442 mL, 3.17 mmol). The mixture was cooled to 0° C. and added with BOP reagent (420 mg, 0.951 mmol). The reaction mixture was then stirred at rt overnight, and then diluted with water. The solid was filtered and dried under suction to obtain the title compound as a light yellow solid. Yield: 350 mg (94%). 1H NMR (400 MHz, DMSO-d6) δ ppm: 12.52 (br. s, 1H) 8.93 (s, 1H) 8.70 (s, 2 H) 8.49 (s, 1H) 8.00-8.14 (m, 2H) 7.88 (d, J=2.51 Hz, 1H) 7.74 (s, 1H) 7.52 (dd, J=8.53, 2.51 Hz, 1H) 7.34-7.43 (m, 4H) 7.20 (s, 1H) 3.89 (s, 3H) 1.54-1.68 (m, 2H) 1.36-1.49 (m, 2H). LCMS: (ES+) m/z=591.39 (M+H)+; Column—ACQUITY UPLC BEH C8 (50×2.1 mm; 1.7 μm); Mphase A: 5 mM Ammonium Acetate:MeCN (95:5); Mphase B: 5 mM Ammonium Acetate: MeCN (5:95)
