Reaction Steps

To a solution of methyl 3-chloro-2-(4-fluorophenyl)quinoxaline-6-carboxylate (200 mg, 0.95 mmol) in DMSO (5 mL) was added DIEA (245 mg, 1.90 mmol) and pyridin-2-ylmethanamine (124 mg, 1.15 mmol), and the reaction was stirred overnight at 90° C. in an oil bath. The solids were precipitated from water (50 mL), collected by filtration, washed with AcOEt (10 mL), and dried to afford methyl 2-(4-fluorophenyl)-3-[(pyridin-2-ylmethyl)amino]quinoxaline-6-carboxylate as a yellow solid (200 mg, 81%).
