A solution of methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv) in DMF (8 mL), 1-(4-(trifluoromethyl)phenyl)piperazine (202 mg, 0.88 mmol, 2.00 equiv), DIEA (170.3 mg, 1.32 mmol, 3.00 equiv) were placed in a 20-mL sealed tube and stirred overnight at 100° C. in an oil bath. The reaction was then quenched by the addition of water. The resulting solution was extracted with 4×50 mL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate followed by filtration to remove solids. The resulting mixture was concentrated under vacuum, resulting in 177.4 mg (78%) of methyl 2-phenyl-3-(4-(4-(trifluoromethyl)phenyl)piperazin-1-yl)quinoxaline-6-carboxylate as a yellow solid.
