To prepare 4- (pyridine-4-yl) -1,3-thiazole-2-mercaptan, there are two common methods.
First, use 4-pyridine formaldehyde and thioacetamide as starting materials. First, put 4-pyridine formaldehyde and thioacetamide in a suitable reaction vessel, add an appropriate amount of solvent, such as ethanol or dimethylformamide, and heat and stir at a certain temperature. This reaction requires fine temperature control, generally at 60-80 degrees Celsius. During the reaction, the aldehyde group of 4-pyridine formaldehyde interacts with the active group of thioacetamide, and through complex chemical changes, the target product 4- (pyridine-4-yl) -1,3-thiazole-2-thiol is gradually formed. During this process, the polarity of the solvent, the reaction temperature and time all have a great influence on the reaction. If the temperature is too low, the reaction rate is slow; if the temperature is too high, side reactions may occur, resulting in a decrease in product purity. The reaction time is about 4-6 hours. After cooling, filtration, washing, drying and other steps, the crude product can be obtained, and then purified by recrystallization and other means to improve the purity of the product.
Second, 4-halopyridine and 2-mercaptothiazole compounds are used as raw materials. Mix 4-halopyridine (such as 4-chloropyridine or 4-bromopyridine) with 2-mercaptothiazole compounds in the reaction system, and add bases such as potassium carbonate or sodium carbonate to promote the reaction. At the same time, adding a phase transfer catalyst, such as tetrabutylammonium bromide, can speed up the reaction rate. The reaction solvent can be acetonitrile or toluene, and the reaction is reacted under heating reflux conditions. In this reaction, the halogen atom of halopyridine reacts with the mercapto group of 2-mercaptothiazole to form the target molecular structure. The reaction temperature is about 80-100 degrees Celsius, and the reaction time is about 6-8 hours. After the reaction is completed, the organic phase is extracted, washed, dried, and then separated and purified by column chromatography. Pure 4- (pyridine-4-yl) -1,3-thiazole-2-thiol can be obtained. The two methods have their own advantages and disadvantages. In actual operation, it is necessary to comprehensively consider the availability of raw materials, cost, product purity requirements and other factors to choose the appropriate one.
