A mixture of 2-bromo-N-(3-(quinoxalin-2-yl)phenyl)acetamide (100 mg, 0.292 mmol), potassium carbonate (51 mg, 0.365 mmol) and 1-(4-pyridyl)-piperazine (50 mg, 0.307 mmol) in acetonitrile (5 mL) was heated at reflux for 15 min. The solvent was evaporated in vacuo and the crude reaction mixture was purified by preparative LCMS to afford 2-(4-(pyridin-4-yl)piperazin-1-yl)-N-(3-(quinoxalin-2-yl)phenyl)acetamide (30 mg, 24% yield). LCMS calculated for C25H24N6O (M+H): 425.50. found 425.44. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.04 (1H, br.), 9.52 (1H, s), 8.58 (1H, m), 8.15-8.10 (4H, m), 8.05-8.08 (1H, m), 7.82-7.95 (3H, m), 7.55-7.60 (1H, m), 6.85 (2H, m), 3.45 (4H, m), 3.25 (2H, s), 2.72 (4H, m).
