2-(2-pyridyl)thiazole and the conversion of this base and of 4-methyl-2-(2-pyridyl)thiazole into a variety of substituted pyrido[1,2-a]thiazolo[2,3-c]pyrazidi-inium salts is described. Attempts to convert 4-phenyl-2-(2-pyridyl)thiazole into the corresponding bridged aromatic diquaternary salts were unsuccessful. The synthesis of 2-methyl-4-(2-pyridyl)thiazole and its conversion into several substituted
2-(2-吡啶基)噻唑的合成以及该碱和4-甲基-2-(2-吡啶基)噻唑的转化为各种取代的吡啶并[1,2- a ]噻唑并[2,3- ç ] pyrazidi-鎓盐进行说明。将4-苯基-2-(2-吡啶基)噻唑转化为相应的桥连芳族二季盐的尝试未成功。还记录了2-甲基-4-(2-吡啶基)噻唑的合成及其转化为几种取代的吡啶并[1,2- a ]噻唑洛- [4,3 - c ]吡唑鎓-铟盐。
