Reaction Steps

Into a 50-mL round-bottom flask, was placed a solution of N-(3-(trifluoromethyl)benzyl)-2-(2-(2-(chloromethyl)picolinamido)-5-(piperidin-1-yl)phenyl)isonicotinamide (100 mg, 0.15 mmol, 1.00 equiv, 90%) in N,N-dimethylformamide (3 mL), (S)—N-(pyrrolidin-3-yl)acetamide (42 mg, 0.33 mmol, 2.00 equiv), potassium carbonate (45 mg, 0.33 mmol, 2.00 equiv), and potassium iodide (14 mg, 0.08 mmol, 0.50 equiv). The resulting solution was stirred for 3 h at 60° C. in an oil bath. The resulting solution was diluted with 100 mL of ethyl acetate. The resulting mixture was washed with 2×20 mL of brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. The crude product (100 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 (39%) of a yellow solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 8.92 (d, J=6 Hz, 1H), 8.42 (s, 1H), 8.19 (m, 1H), 8.15 (m, 1H), 8.10 (m, 1H), 8.04 (m, 1H), 7.83 (d, J=6 Hz, 1H), 7.74 (m, 3H), 7.61 (m, 2H), 7.52 (m, 1H), 4.65 (m, 4H), 4.22 (m, 1H), 3.80 (m, 1H), 3.69-3.54 (m, 5H), 3.44 (m, 1H), 2.49 (m, 1H), 2.05-2.00 (m, 5H), 1.83-1.66 (m, 5H). MS (ES, m/z): 700 [M+H]+.
