The synthesis method of 2-bromo-4-phenyl-1,3-thiazole is described in the past books, and there are about the following numbers.
First, sulfur-containing compounds and halogenated acetophenone are used as starting materials. First, take an appropriate amount of sulfur-containing compounds, such as thiourea, and mix them with halogenated acetophenone in a specific solvent. This solvent is often selected from ethanol, dichloromethane, etc. Its polarity is moderate, which can fully dissolve the reactants and facilitate the reaction. Then, add an appropriate amount of alkali, such as sodium carbonate, potassium carbonate, etc., to adjust the pH of the reaction system and promote the reaction. At a suitable temperature, it is generally heated to reflux to make the two fully react. In this process, the sulfur atom of thiourea and the carbonyl group of halogenated acetophenone undergo nucleophilic addition, and then cyclize to form a thiazole ring, and the final product is 2-bromo-4-phenyl-1,3-thiazole.
Second, use 2-amino-4-phenyl-1,3-thiazole as raw material. Place it in a suitable reaction vessel and add appropriate brominating reagents, such as bromine, N-bromosuccinimide (NBS), etc. If bromine is used, it needs to be handled with caution because of its strong oxidizing and corrosive properties. Take NBS as an example, it is a milder brominating agent. Under the protection of inert gas, such as nitrogen environment, in an organic solvent, such as carbon tetrachloride, the reaction temperature is controlled, usually between room temperature and 50 ° C, and a brominating reagent is slowly added dropwise. In this reaction, the amino ortho-hydrogen atom of 2-amino-4-phenyl-1,3-thiazole is replaced by a bromine atom to obtain 2-bromo-4-phenyl-1,3-thiazole.
Third, a thiazole ring is constructed through a multi-step reaction. First, benzaldehyde and thioglycolic acid are used as raw materials, and under the action of a condensing agent, such as dicyclohexyl carbodiimide (DCC), they react in an organic solvent to form an intermediate product. This intermediate product is further reacted with brominating reagents and other nitrogen-containing reagents, such as cyanamide, under basic conditions, and then gradually synthesized 2-bromo-4-phenyl-1,3-thiazole through cyclization and other steps. Although this method has many steps, it can precisely control the reaction and improve the purity and yield of the product.
