Reaction Steps

2-Chloro-7-methoxyquinoxaline (0.51 g, 2.62 mmol), prepared according to J. Chem. Soc. Perk Trans. 1, 2001, 978-984, and (2,4-dimethoxyphenyl)methanamine (1.181 mL, 7.86 mmol) were microwaved in DMSO (2.5 mL) for 30 min at 150° C. This was diluted into 150 mL EtOAc and extracted three times with 100 mL brine. The crude product was purified by flash chromatography on a 90 g silica gel cartridge with 20 to 80% EtOAc in hexane, 50 min, at 40 mL/min to afford N-(2,4-dimethoxybenzyl)-7-methoxyquinoxalin-2-amine (795 mg, 2.443 mmol, 93% yield).
