Reaction Steps
Into a 10-mL sealed tube, was placed methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), cyclohexanamine (131.03 mg, 1.32 mmol, 3.00 equiv), potassium carbonate (304.41 mg, 2.21 mmol, 5.00 equiv), and N,N-dimethylformamide (2 mL). The resulting solution was stirred overnight at 100° C. in an oil bath. The reaction was then quenched by the addition of 20 mL of water. The resulting aqueous solution was extracted with 3×50 mL of ethyl acetate. The organic layers were combined and washed with 5×30 mL of aq. sodium chloride. The organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography with ethyl acetate/petroleum ether (1:50). This resulted in 80 mg (46%) of methyl 3-(cyclohexylamino)-2-phenylquinoxaline-6-carboxylate as a yellow solid.
