The synthesis of 4-methyl pyrido[3, 2-e]pyrrolo[1, 2-a]pyrazines was described. The starting material, 2-amino-4-methyl-3-nitropyridine, was converted into pyrrolyl derivative by using 2, 5-dimethoxytetrahydrofuran in glacial acetic aicd. Subsequent cyclization of the latter afforded the title compounds. The proton nuclear magnetic resonance spectra of the products was also studied.
报道了4-甲基吡啶并[3,2-e]吡咯并[1,2-a]吡嗪的合成。起始原料2-氨基-4-甲基-3-硝基吡啶通过使用冰乙酸中的2,5-二甲氧基四氢呋喃转化为吡咯啉衍生物。后者的环合反应得到了目标化合物。还研究了产物的质子核磁共振谱。
