Reaction Steps

Into a 10-mL sealed tube, was placed methyl 3-chloro-2-phenylquinoxaline-6-carboxylate (150 mg, 0.50 mmol, 1.00 equiv), 2-(2-bromophenyl)ethanamine (300.5 mg, 1.51 mmol, 3.00 equiv), potassium carbonate (347.3 mg, 2.52 mmol, 5.00 equiv), toluene/DMSO (5/1 mL). The resulting solution was stirred for overnight at 100° C. in an oil bath. The resulting mixture was concentrated under vacuum and applied onto a silica gel column with ethyl acetate/petroleum ether (1:50). This resulted in 110 mg (47%) of methyl 3-(2-bromophenethylamino)-2-phenylquinoxaline-6-carboxylate as a yellow solid.
