Reaction Steps
To a solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (50 mg, 0.15 mmol, 1.00 equiv) in DMF (10 mL) was added 1-phenylpiperazine (50 mg, 0.31 mmol, 2.00 equiv) and DIEA (100 mg, 0.78 mmol, 5.3 equiv). The resulting solution was placed in a 20-mL sealed tube, stirred overnight at 100° C. in an oil bath, then concentrated under vacuum. Purification via silica gel column (ethyl acetate/petroleum ether (1:10)) yielded 70 mg (crude) of methyl 2-phenyl-3-(4-phenylpiperazin-1-yl)quinoxaline-6-carboxylate as a yellow solid.
