To a mixture of 2-(4-(2-methylpyridin-4-yl)phenyl)acetic acid 26-3 (22 mg, 0.1 mmol), 4-(6-aminopyridin-3-yl)piperazin-2-one 141-4 (19 mg, 0.1 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (HATU) (40 mg, 0.1 mmol) in DMF (1 mL) was added DIEA (52 μL, 0.3 mmol) at room temperature. The mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted into DMSO and purified by reverse phase HPLC to give 2-(4-(2-methylpyridin-4-yl)phenyl)-N-(5-(3-oxopiperazin-1-yl)pyridin-2-yl)acetamide 141. MS m/z 402.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ10.53 (s, 1H), 8.49 (d, 1H), 8.05-8.01 (m, 2H), 7.94 (d, 1H), 7.75 (d, 2H), 7.57 (s, 1H), 7.48-7.48 (m, 3H), 7.41 (dd, 1H), 3.74 (s, 1H), 3.71 (s, 2H), 2.54-2.50 (m, 7H), 1.24 (s, 2H).
