cetic acid with the corresponding N-substituted piperazines. The 13C NMR spectra and mass spectra of the compounds were measured and signals were assigned. Some of the compounds showed inhibitory action on contractile function of smooth muscle.
通过用氯甲酸乙酯和KOH在乙醇中的处理,由相应的N-取代的2-氨基苯甲酰胺制备3-取代的2,4(1H,3H)-喹唑啉二酮。另外,通过1-甲基-1,4-二氢-和1,4-二氢-2的反应合成了一系列3-取代和1-甲基-3-取代的2,4(1H,3H)-喹唑啉二酮。 ,4-二氧代-3(2H)-喹唑啉乙酸与相应的N-取代的哌嗪。测量化合物的13 C NMR光谱和质谱,并分配信号。一些化合物对平滑肌的收缩功能显示出抑制作用。
