Into a 50-mL vial, was placed N-(3-(trifluoromethyl)benzyl)-2-(2-(2-((methylamino)methyl)picolinamido)-5-(piperidin-1-yl)phenyl)isonicotinamide (100 mg, 0.17 mmol, 1.00 equiv) in dichloromethane (10 mL), 2-morpholinoacetic acid (28.9 mg, 0.20 mmol, 1.20 equiv), EDC.HCl (47.4 mg, 0.25 mmol, 1.50 equiv), and 4-dimethylaminopyridine (30.4 mg, 0.25 mmol, 1.50 equiv). The resulting solution was stirred for 4 h 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 3×50 mL of aqueous NH4Cl, dried over anhydrous sodium sulfate, and concentrated under vacuum. The crude product (200 mg) was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 116 mg (59%) of a yellow solid. 1H-NMR (400 MHz, CD3OD, ppm): δ 9.12 (m, 1H), 8.86 (d, J=9.2 Hz, 1H), 8.34 (d, J=2.0 Hz, 1H), 8.17 (m, 1H), 8.12 (m, 1H), 8.01 (m, 1H), 7.95 (m, 1H), 7.80 (m, 3H), 7.60 (m, 3H), 4.96 (m, 2H), 4.72 (s, 2H), 4.50 (m, 2H), 3.98 (m, 4H), 3.70 (m, 4H), 3.1 (s, 3H), 2.10 (m, 4H), 1.98 (s, 2H). MS (ES, m/z): 730 [M+H]+.
