Reaction Steps

Into a 8-mL sealed tube, was placed methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), 2-(piperazin-1-yl)pyrimidine (144.3 mg, 0.88 mmol, 2.00 equiv), DIEA (170.3 mg, 1.32 mmol, 3.00 equiv), N,N-dimethylformamide (3 mL). The resulting solution was stirred overnight at 100° C. in an oil bath. The resulting solution was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:50). This resulted in 192 mg (95%) of methyl 2-phenyl-3-(4-(pyrimidin-2-yl)piperazin-1-yl)quinoxaline-6-carboxylate as a yellow solid.
