Reaction Steps

A slurry of 2-chloro-N-(3-quinoxalin-2-ylphenyl)acetamide (100 mg, 0.336 mmol), 1-(4-chlorophenyl)piperazine dihydrochloride (100 mg, 0.367 mmol) and K2CO3 (149 mg, 1.075 mmol) in MeCN (5 mL) was heated at reflux for 24 hrs. The reaction mixture was diluted with ethyl acetate (20 mL), and the organic phase washed with water (20 mL) and then brine (20 mL), dried over MgSO4 and evaporated in vacuo. The residue was triturated with diethyl ether and dried in vacuo at 50° C. to afford 2-[4-(4-chlorophenyl)piperazin-1-yl]-N-(3-(quinoxalin-2-yl)phenyl)acetamide (56 mg, 36% yield). LCMS calculated for C26H24ClN5O (M+H): 458.17. found 458.21. 1H-NMR (DMSO-d6, 400 Mhz) δH: 10.00 (1H, br. s), 9.51 (1H, s), 8.55 (1H, m), 8.15-8.10 (2H, m), 8.05 (1H, d, 1=7.5 Hz), 7.95-7.80 (3H, m), 7.55 (1H, m), 7.21 (2H, d, J=7.5 Hz), 6.90 (2H, d, J=7.5 Hz), 3.21 (4H, m), 2.61 (4H, m).
