Into a 50-mL round-bottom flask, was placed a solution of N-(3-(trifluoromethyl)benzyl)-2-(2-(3-(bromomethyl)benzamido)-5-(piperidin-1-yl)phenyl)isonicotinamide (100 mg, 0.15 mmol, 1.00 equiv) in N,N-dimethylformamide (2 mL), N-(piperidin-4-yl)acetamide (52.5 mg, 0.37 mmol, 2.41 equiv), potassium iodide (12.7 mg, 0.08 mmol, 0.50 equiv), and potassium carbonate (42.4 mg, 0.31 mmol, 2.00 equiv). The resulting solution was stirred for 3 h at 70° C. in an oil bath. The reaction progress was monitored by LCMS. The resulting solution was diluted with 20 mL of water. The resulting solution was extracted with 3×20 mL of ethyl acetate and the organic layers combined. The resulting mixture was washed with 3×20 mL of brine. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The crude product was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 80.4 mg (50%) of a yellow solid. 1H-NMR (400 MHz, CD3OD, ppm): δ 8.93-8.92 (d, J=5.2 Hz, 1H), 8.67-8.65 (d, J=8.8 Hz, 1H), 8.44 (s, 1H), 8.13-8.09 (m, 3H), 7.88-7.87 (m, 1H), 7.78-7.67 (m, 5H), 7.62-7.54 (m, 1H), 4.72 (s, 2H), 4.44 (s, 2H), 3.91 (s, 1H), 3.66-3.63 (t, J=5.2 Hz, 4H), 3.57-3.54 (m, 2H), 3.20-3.14 (m, 2H), 2.17-2.13 (m, 2H), 2.05-2.00 (m, 4H), 1.93 (s, 3H), 1.82-1.70 (m, 4H). MS (ES, m/z): 713 [M+H]+.
