Reaction Steps

Into a 8-mL sealed tube, was placed methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.439 mmol, 1.00 equiv), (S)-butan-2-amine (2 mL), DMSO (1 mL). The resulting solution was stirred overnight at 60° C. in an oil bath. The resulting mixture was concentrated under vacuum and diluted with H2O. The resulting solids were collected by filtration. The residue was applied onto a silica gel column with PE/EA (50:1). This resulted in 114 mg of (R)-methyl 3-(sec-butylamino)-2-phenylquinoxaline-6-carboxylate as yellow oil.
