Procedure
To a mixture of 2-(2′-fluoro-2,4′-bipyridin-5-yl)acetic acid 208-3 (42 mg, 0.18 mmol), 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone 111-4 (40 mg, 0.18 mmol), o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 68 mg, 0.18 mmol) were added DMF (1 mL) and diispropylethyl amine (DIEA, 0.15 mL, 0.9 mmol) and the mixture was stirred at room temperature overnight. The crude product, a clear DMF solution, was subjected directly for reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(2′-fluoro-2,4′-bipyridin-5-yl)acetamide 209 as white solid. MS m/z 435.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 10.65 (s, 1H), 8.69 (d, 1H), 8.36 (d, 1H), 8.15 (d, 1H), 8.05-8.02 (m, 2H), 7.94-7.90 (m, 2H), 7.81 (s, 1H), 7.42 (dd, 1H), 3.83 (s, 2H), 3.57-3.54 (m, 4H), 3.15-3.13 (m, 2H), 3.09-3.06 (m, 2H), 2.03 (s, 3H).
