Reaction Steps

A solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (50 mg, 0.15 mmol, 1.00 equiv), 1-(pyridin-2-yl)piperazine (50 mg, 0.31 mmol, 2.00 equiv), and DIEA (100 mg, 0.78 mmol, 3.00 equiv) in DMF (10 mL) was placed in a 20-mL sealed tube under an inert atmosphere and stirred overnight at 100° C. in an oil bath and then concentrated under vacuum. Purification via silica gel column (ethyl acetate/petroleum ether (1:10)) yielded 68 mg (crude) of methyl 2-phenyl-3-(4-(pyridin-2-yl)piperazin-1-yl)quinoxaline-6-carboxylate as a yellow solid
