Reaction Steps

Into a 20-mL sealed tube, was placed methyl 3-chloro-2-phenylquinoxaline-6-carboxylate (180 mg, 0.60 mmol, 1.00 equiv), toluene/DMSO (5/1 mL), 3-(2-bromophenyl)propan-1-amine (385 mg, 1.80 mmol, 2.99 equiv), and potassium carbonate (414 mg, 3.00 mmol, 4.98 equiv). The resulting solution was stirred overnight at 100° C. The mixture was concentrated under vacuum. The residue was purified by silica gel chromatography with ethyl acetate/petroleum ether (1:50). This resulted in 240 mg (80%) of methyl 3-(3-(2-bromophenyl)propylamino)-2-phenylquinoxaline-6-carboxylate as a yellow solid.
