Reaction Steps

A solution of 2-chloro-N-(3-quinoxalin-2-ylphenyl)acetamide (100 mg, 0.336 mmol) and N-methylpiperazine (79 μL, 0.706 mmol) in ethanol (5 mL) was heated at 100° C. for 18 hrs. The solvent was evaporated and the oily residue was submitted to preparative LCMS to afford 2-(4-methylpiperazin-1-yl)-N-[3-(quinoxalin-2-yl)phenyl]acetamide (42 mg, 34%). LCMS calculated for C21H23N5O (M+H): 362.19. found 362.16. 1H-NMR (DMSO-d6, 400 Mhz) δH: 9.90 (1H, br. s), 9.51 (1H, s), 8.54 (1H, m), 8.19-8.12 (2H, m), 8.08 (1H, d, J=7 Hz), 7.94-7.82 (3H, m), 7.55 (1H, m), 3.18 (2H, s), 2.60-2.53 (4H, br), 2.48-2.40 (4H, br), 2.20 (3H, s).
