Formation of 5-acetamido-substituted thiazoles was found to be readily effective on heating 2-(acylamino)thioacetamides with acetic anhydride. In additon, preparation of some starting 2-(acylamino)thioacetamides is described and 5-acetamidothiazole-4-carboxamides obtained by the thiazole formation reaction were led to some thiazolo[5, 4-d]pyrimidines.
研究发现,用乙酸酐加热 2-(酰氨基)硫代乙酰胺很容易生成 5-乙酰胺基取代的噻唑。此外,还介绍了一些 2-(酰氨基)硫代乙酰胺起始物的制备方法,并通过噻唑形成反应获得了 5-乙酰胺基噻唑-4-甲酰胺,从而得到了一些噻唑并[5, 4-d]嘧啶。
