Reaction Steps

A slurry of 2-chloro-N-(3-quinoxalin-2-ylphenyl)acetamide (100 mg, 0.336 mmol) and piperazine (58 mg, 0.672 mmol) in MeCN (5 mL) was heated at reflux for 48 hrs. The resulting precipitate was filtrated, washed with MeCN (10 mL) and submitted to preparative LCMS to afford 2-(piperazin-1-yl)-N-(3-(quinoxalin-2-yl)phenyl)acetamide (46 mg, 39% yield). LCMS calculated for C20H21N5O (M+H): 348.42. found 348. 1H-NMR (DMSO-d6, 400 Mhz) δH: 9.92 (1H, br.), 9.52 (1H, s), 8.55 (1H, m), 8.13-8.20 (2H, m), 8.05-8.08 (1H, m), 7.82-7.98 (3H, m), 7.55-7.60 (1H, m), 3.25-3.40 (NH and 6H, br.), 2.80-2.88 (4H, br.).
