6-Bromopyridine-2-carboxylic acid ethyl ester

The synthesis method of 6-bromopyridine-2-carboxylate ethyl ester has been around for a long time, and there are many changes. Common methods are obtained by bromination with pyridine-2-carboxylate ethyl ester as the starting material. The method is as follows:
In a suitable reaction vessel, put pyridine-2-carboxylate ethyl ester and dissolve it in a suitable solvent, such as dichloromethane, chloroform and other inert organic solvents. Then, under low or normal temperature conditions, slowly add brominating reagents, common brominating reagents such as N-bromosuccinimide (NBS), or liquid bromine. If N-bromosuccinimide is used, the reaction is relatively mild and easy to control; if liquid bromine is used, the reaction activity is higher, but it needs to be handled with caution to prevent side reactions. During the reaction process, it is often necessary to add initiators, such as benzoyl peroxide, to promote the reaction. At the same time, the reaction process needs to be monitored by appropriate means, such as thin layer chromatography (TLC), and the reaction is stopped when the raw materials are completely consumed. After the reaction, the pure 6-bromopyridine-2-carboxylate can be obtained by regular separation and purification methods, such as extraction, washing, drying, column chromatography, etc.
Another method is to prepare the esterification reaction of 6-bromopyridine-2-carboxylic acid with ethanol under acid catalysis. 6-bromopyridine-2-carboxylic acid and excess ethanol are placed in a reactor, and an appropriate amount of acid catalyst is added, such as concentrated sulfuric acid, p-toluenesulfonic acid, etc. The reaction system is refluxed by heating. During this process, the acid catalyst can promote the esterification reaction of carboxylic acid and alcohol. After the reaction is completed, the excess ethanol is evaporated first, and then the remaining product is purified, such as alkaline washing, water washing to remove residual acid, and then drying, distillation or recrystallization. Ethyl 6-bromopyridine-2-carboxylate can also be obtained. These two methods have their own advantages and disadvantages, and they should be used according to the actual situation.
