2-氨基噻唑簡(jiǎn)介

2-Aminothiazole is a heterocyclic amine featuring an thiazole core. It can also be considered a cyclic isothiourea. It possesses an odor similar to pyridine and is soluble in water, alcohols and diethyl ether. It is commonly used as a starting point for the synthesis of many compounds including sulfur drugs, biocides, fungicides, dyes and chemical reaction accelerators. 2-Aminothiazole can be used as a thyroid inhibitor in the treatment of hyperthyroidism and has antibacterial activity. Alternatively, its acid tartrate salt can be used. Recent studies using prion-infected neuroblastoma cell lines have suggested that aminothiazole may be used as a therapeutic drug for prion diseases.

生產(chǎn)方法及用途

生產(chǎn)方法

由硫脲與氯乙醛(或乙醇和氯氣,或α,β二氯乙基乙醚)經(jīng)環(huán)合而得。在反應(yīng)器中加入熱水、硫脲和α,β-二氯乙基乙醚。在攪拌下回流2h。冷卻,經(jīng)滴液漏斗加入氫氧化鈉溶液,使溶液呈堿性,析出2-氨基噻唑晶體。然后加入乙醚使之溶解。分出醚層,用水洗滌后,以無(wú)水硫酸鈉干燥,蒸出乙醚得粗品。用乙醇重結(jié)晶,得黃色晶體。產(chǎn)率為80%,熔點(diǎn)90℃。
