Interaction of 5-diazoimidazole-4-carboxamide and alkyl and aryl isocyanates in the dark affords 8-carbamoyl-3-substituted-imidazo[5,1-d]-1,2,3,5-tetrazin-4(3H)-on es. In cold methanol or ethanol, the 3-(2-chloroethyl) derivative 7a decomposes to afford 2-azahypoxanthine (14) and methyl and ethyl N-(2-chloroethyl)carbamates, respectively. Compound 7a has curative activity against L-1210 and P388 leukemia
5-重氮咪唑-4-羧酰胺与烷基和芳基异氰酸酯在黑暗中的相互作用提供了8-氨基甲酰基-3-取代的咪唑并[5,1-d] -1,2,3,5-四嗪-4(3H)-那些。在冷甲醇或乙醇中,3-(2-氯乙基)衍生物7a分解,分别得到2-氮杂y吨黄嘌呤(14)和N-(2-氯乙基)氨基甲酸甲酯和乙酯。化合物7a对L-1210和P388白血病具有治愈活性,并且可以作为无环三氮烯5- [3-(2-氯乙基)三氮杂-1-基]咪唑-4-羧酰胺(MCTIC)的前药修饰开环形成碳酸钠水溶液中的三氮烯。
