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), butan-2-amine (193 mg, 2.64 mmol, 6.00 equiv), potassium carbonate (181.6 mg, 1.32 mmol, 3.00 equiv), toluene (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 (1:10). This resulted in 109 mg (crude) of methyl 3-(sec-butylamino)-2-phenylquinoxaline-6-carboxylate as yellow oil.
