By the application of sodium hydroxide, 2′-amino-6-chloro (methoxy, ethoxy) pyrido-2, 3:5′, 4′-thiazole was decomposed to 2-mercapto-3-amino-6-chloro (methoxy, ethoxy)-pyridine and treated with acetic anhydride to obtain 2-acetylmercapto-3-acetamino-6-chloro (methoxy, ethoxy) pyridine and 2′-methyl-6-chloro (methoxy, ethoxy) pyrido-2, 3:5′, 4′-thiazole. 2-Acetylmercapto-3-acetamino-6-chloropyridine is hydrolyzed by cold sodium hydroxide solution to 2-mercapto-3-acetamino-6-chloropyridine which is then oxidized by ferric chloride to 3, 3′-diacetamino-6, 6′-dichloropyridine-2, 2′-disulfide.
