Reaction Steps

To a solution of methyl 3-chloro-2-oxo-1,2-dihydroquinoxaline-6-carboxylate (3 g, 12.57 mmol) in DMSO (20 ml) was added methyl(propan-2-yl)amine (1.3 g, 17.77 mmol), and DIEA (3.2 g, 24.76 mmol). The resulting solution was stirred overnight at 70° C. The product was precipitated by the addition of ice/water and collected by filtration to afford methyl 3-[methyl(propan-2-yl)amino]-2-oxo-1,2-dihydroquinoxaline-6-carboxylate as a yellow solid (2.5 g, 72%).
