Reaction Steps
5-Bromopyrazin-2-amine (0.11 g, 0.63 mmol) was dissolved in NaOMe/MeOH (0.23 g Na metal in 10 mL MeOH) and heated by microwave irradiation at 140° C. for 7 hours. After evaporation of the solvent, the residue was purified by preparative TLC, eluting with 30% ethyl acetate-n-hexane, to give 5-methoxypyrazin-2-amine (25 mg, 32%).
