Reaction Steps
Into a 8-mL sealed tube, was placed a solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv) in N,N-dimethylformamide (3 mL), diethylamine (63.4 mg, 0.87 mmol, 2.00 equiv), and DIEA (170.3 mg, 1.32 mmol, 3.00 equiv). 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 and eluted with ethyl acetate/petroleum ether (1:100). This resulted in 117 mg (80%) of methyl 3-(diethylamino)-2-phenylquinoxaline-6-carboxylate as a yellow oil.
