Procedure

Into a 10-mL round bottom flask, was placed a solution of 3-((2-(4-((3-(trifluoromethyl)benzyl)carbamoyl)pyridin-2-yl)-4-(piperidin-1-yl)phenyl)carbamoyl)-benzoic acid (100 mg, 0.17 mmol, 1.00 equiv) in dichloromethane (5 mL), EDC.HCl (63.75 mg, 0.33 mmol, 2.00 equiv), 4-dimethylaminopyridine (40.5 mg, 0.33 mmol, 2.00 equiv), N1,N1-diethyl-N2-methylethane-1,2-diamine (64.8 mg, 0.56 mmol, 3.00 equiv). The resulting solution was stirred overnight at 25° C. in an oil bath. The reaction progress was monitored by LCMS. The resulting solution was diluted with 50 mL of dichloromethane. The resulting mixture was washed with 3×70 mL of NH4Cl (aq). The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The crude product (150 mg) was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 47.8 mg (34%) of a yellow solid. 1H-NMR (300 MHz, DMSO-d6, ppm): δ 12.36 (s, 1H), 9.57 (t, 1H), 9.28 (s, 1H), 8.90 (d, J=5.1 Hz, 1H), 8.30 (m, 2H), 7.98 (d, J=7.2 Hz, 2H), 7.84 (d, J=4.8 Hz, 1H), 7.65 (m, 7H), 7.28 (d, J=8.4 Hz, 1H), 4.66 (d, J=6.0 Hz, 2H), 3.82 (m, 2H), 3.31 (m, 9H), 2.97 (s, 4H), 1.71 (m, 6H), 1.24 (m, 6H). MS (ES, m/z): 715 [M+H]+.
