Reaction Steps

Into a 10-mL sealed tube, was placed methyl 2-chloro-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylate (110 mg, 0.38 mmol, 1.00 equiv), 3-fluorophenylboronic acid (157.4 mg, 1.12 mmol, 3.00 equiv), Pd(PPh3)4 (86.5 mg, 0.07 mmol, 0.20 equiv), K3PO4 (318 mg, 1.51 mmol, 4.00 equiv), 1,4-dioxane (4 mL). The resulting solution was stirred for overnight at 100° C. in an oil bath. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:30). This resulted in 75 mg (57%) of methyl 2-(3-fluorophenyl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylate as a yellow solid.
