Reaction Steps

A solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), 1-(4-chlorophenyl)piperazine (172.5 mg, 0.88 mmol, 5.00 equiv), and DIEA (170.3 mg, 1.32 mmol, 3.00 equiv) in DMF (4 mL) was placed in a 8-mL sealed tube, stirred overnight at 100° C. in an oil bath, then concentrated under vacuum. Purification via silica gel column (ethyl acetate/petroleum ether (1:50)) afforded 153.4 mg (69%) of methyl 3-(4-(4-chlorophenyl)piperazin-1-yl)-2-phenylquinoxaline-6-carboxylate as a yellow solid.
