Attempts to prepare oxazolo [4, 5-d] pyrimidines by the reaction of 2, 4-diamino-5-hydroxy-6-methylpyrimidine (I) with aromatic carboxylates. The products were carbinolamines which were converted to oxazolo [4, 5-d] pyrimidines. Also, the application of the Salol reaction of I gave 5-amino-2-(2, 4-diamino-6-methylpyrimidin-5-yl)oxy-2-o-hydroxyphenyl-7-methyl-3H-oxazolo [4, 5-d] pyrimidine (XI) which was an unusual product in this reaction.
尝试通过2, 4-二氨基-5-羟基-6-甲基嘧啶(I)与芳香羧酸酯反应来合成氮杂环[4, 5-d]嘧啶。产物为碳醇胺,随后转化为氮杂环[4, 5-d]嘧啶。此外,I的Salol反应的应用产生了5-氨基-2-(2, 4-二氨基-6-甲基嘧啶-5-基)氧-2-o-羟基苯基-7-甲基-3H-氮杂环[4, 5-d]嘧啶(XI),这是该反应中一个不寻常的产物。
