The reaction of 2-aminothiazoles with ethyl acetoacetate in acetic or polyphosphoric acid gave a series of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives which were nitrated with a mixture of nitric and sulfuric acid to 6-nitro-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-ones, and the latter were reduced to the corresponding amines.
2-氨基噻唑与乙酰乙酸乙酯在乙酸或多磷酸中的反应生成一系列5 H- [1,3]噻唑并[3,2 - a ]嘧啶-5-酮衍生物,将其用硝酸和硫酸的混合物进行硝化酸生成6-硝基-5 H- [1,3]噻唑并[3,2 - a ]嘧啶-5-酮,然后将后者还原为相应的胺。
