摘要: 研究了3-氧代-2,3-二氢-6-甲硫基吡唑[3,4-e]并-1,2,4-三嗪的合成及其对酸、碱的不稳定性、对胺的取代反应以及关键性中间体-3,5-二甲硫基-1,24-三嗪-6-羧酸乙酯的亲核性取代反应活性。

Abstract: 3-Oxo-2,3-dihydro-6-methylthio-pyrazolo(3,4-e)-l,2,4-triazine was prepared. Its stability to diluted acid and base and substitution reaction, with amines were studied. The activity of nucleophillic substitution reaction of the key intermediate ethyl 3,5-dimethylthio-1,2,4-triazine-6-carboxylate was investigated.
