0-[5′-(3′-甲硫基-6′-甲基)-1,2,4-三嗪基]-3-甲硫基-5-羟基-6-甲基-1,2,4-三嗪在乙醇中与一系列的胺反应,得到3-甲硫基-5-取代氨基-6-甲基-1,2,4-三嗪及3-甲硫基-5-羟基-6-甲基-1,2,4-三嗪(表1)。我们曾企图将这些5-取代氨基化合物进行水解,但3-甲硫基-5-二乙胺基-6-甲基-1,2,4-三嗪在1N盐酸或1N碳酸钠中回流,或3-甲硫基-5-对甲苯胺基-6-甲基-1,2,4-三嗪在0.1N盐酸中放置,均得到高熔点聚合物。 0-[5′-(3′-甲硫基-6′-甲基)-1,2,4-三嗪基]-3-甲硫基-5-羟基-6-甲基-1,2,4-三嗪与对硝基苯
0- [5 ’- (3’-methylthio-6’-methyl) -1,2,4-triazinyl] -3-methylthio-5-hydroxy-6-methyl-1,2 , 4-triazine was reacted with a series of amines in ethanol to give 3-methylthio-5-substituted amino-6-methyl-1,2,4-triazine and 3-methylthio-5-hydroxy Methyl-1,2,4-triazine (Table 1). We attempted to hydrolyze these 5-substituted amino compounds, but 3-methylthio-5-diethylamino-6-methyl-1,2,4-triazine was refluxed in 1N hydrochloric acid or 1N sodium carbonate, Or 3-methylthio-5-p-toluidino-6-methyl-1,2,4-triazine are placed in 0.1N hydrochloric acid to give a high melting point polymer. 0- [5 ’- (3’-methylthio-6’-methyl) -1,2,4-triazinyl] -3-methylthio-5-hydroxy-6-methyl-1,2 , 4-triazine and p-nitrobenzene
