반응 단계
A mixture of 0.1 mole of 2-amino-3-methoxy-5-bromopyrazine and 0.1 mole of sodium in 160 ml. of anhydrous methanol is refluxed 5-10 hours and poured into water. The product is extracted with ether or chloroform and recrystallized from a suitable solvent such as ethanol to give 2-amino-3,5-dimethoxypyrazine.
