3-Methyl-5-nitroisothiazole has been prepared from diazotised 5-amino-3-methylisothiazole and sodium nitrite. Oxidation gave the 3-carboxylic acid, which was converted into the amide, nitrile, aldehyde, and derivatives. Treatment of 3,5-dichloroisothiazole-4-carbonitrile with sodium nitrite gave 3-chloro-5-hydroxyisothiazole-4-carbonitrile.
3-甲基-5-硝基异噻唑是由重氮化的5-氨基-3-甲基异噻唑和亚硝酸钠制得的。氧化得到3-羧酸,将其转化为酰胺,腈,醛和衍生物。用亚硝酸钠处理3,5-二氯异噻唑-4-腈,得到3-氯-5-羟基异噻唑-4-腈。
