4,5-Dichloro-1,2-thiazol-3-amine was synthesized starting from accessible 4,5-dichloro-1,2-thiazole-3-carbonyl azide and -3-carboxamide via Curtius and Hofmann rearrangements, respectively. The procedure involving Curtius rearrangement was found to be more advantageous from the preparative viewpoint.
从可及的4,5-二氯-1,2-噻唑-3-羰基叠氮化物和-3-羧酰胺分别经Curtius和Hofmann重排合成4,5-二氯-1,2-噻唑-3-胺。从制备的观点来看,发现涉及库尔修斯重排的方法是更有利的。
