実験手順
2-Chloro-7-methylquinoxaline (0.51 g, 2.86 mmol), ), prepared according to J. Chem. Soc. 1948 1310-1313, and (2,4-dimethoxyphenyl)methanamine (1.29 mL, 8.57 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-methylquinoxalin-2-amine (860 mg, 2.78 mmol, 97% yield).
