Several 5-substituted derivatives of 7-ethoxycarbonyl-6,8-dimethyl-1(2H)- phthalazinone were prepared by means of nitration, reductive amination, and diazonium decomposition. The substituents introduced included NO2, NH2, F, Cl, CN. Among the derivatives, the fluorine compound was obtained only in poor yield because intramolecular cyclization occurred predominantly.
通过硝化,还原胺化和重氮鎓分解制备了几种7-乙氧基羰基-6,8-二甲基-1(2H)-酞嗪酮的5-取代衍生物。引入的取代基包括NO 2,NH 2,F,Cl,CN。在这些衍生物中,因为主要发生分子内环化,所以氟化合物的收率很低。
