4-Aminothiazole is prepared in stable useful form by alkaline hydrolysis of 4-trifluoroacetamidothiazole. Also prepared are 4-sulfathiazole and 2-(4-thaizolyl)-indazole.
4-Sulfanilamidothiazole having antibacterial activity is prepared from the previously unknown 4-aminothiazole.
具有抗菌活性的4-磺酰胺基噻唑是由先前未知的4-氨基噻唑制备而成。

The azo couplingreactions of six five-membered ring heteroaromatic diazonium ions with 2-naphthol-3,6-disulfonic acid are investigated kinetically at various pH values. The dependence of the measured rate constants on the acidity of the aqueous reaction system is evaluated. It can be shown that the 2-naphtholate-3,6-disulfonate trianion reacts 4 × 108–8 × 108 times faster than the 2-naphthol-3,6-disulfonate
