The sulfonation of 4-substituted 2-aminothiazoles with chlorosulfonic acid under mild conditions afforded primarily 2-amino-5-thiazolesulfonic acids that at heating in sulfuric acid rearranged into the corresponding stable 2-thiazolesulfamoylic acids.
在温和条件下,使用氯磺酸对4取代的2-氨基噻唑进行磺化,主要得到2-氨基-5-噻唑磺酸,这些化合物在硫酸加热时会重排成相应的稳定2-噻唑磺酰胺酸。
