Reaction Steps

A solution of 4-(4-(trifluoromethyl)phenyl)piperidine (200 mg, 0.87 mmol, 2.00 equiv), methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), and DIEA (169 mg, 1.31 mmol, 3.00 equiv) in DMF (10 mL) was placed in a 20-mL sealed tube and stirred overnight at 100° C. in an oil bath. The resulting mixture was concentrated under vacuum and purified via silica gel column (ethyl acetate/petroleum ether (1:20)), yielding 180 mg (84%) of methyl 2-phenyl-3-(4-(4-(trifluoromethyl)phenyl)piperidin-1-yl)quinoxaline-6-carboxylate as a yellow solid.
