The synthesis of 5-bromo-N-methylpyridine-2-formamide is one of the important topics in organic synthetic chemistry. There are many methods, and one of the commonly used methods is briefly described below.
First, 5-bromopyridine-2-formic acid is used as the starting material, which is the key starting material. It is co-placed in a suitable organic solvent, such as dichloromethane, with an appropriate condensing agent, such as dicyclohexyl carbodiimide (DCC). This organic solvent can fully dissolve the reaction substrate, which is conducive to the reaction.
Then, add N-methylamine. As a nucleophile, N-methylamine can amide with 5-bromopyridine-2-carboxylic acid under the action of a condensing agent. During the reaction, the condensing agent promotes dehydration between the acid and the amine, forming an amide bond, and then forming the target product 5-bromopyridine-2-formamide.
When reacting, pay attention to the control of the reaction temperature. Generally speaking, low temperature can make the reaction proceed smoothly and reduce the occurrence of side reactions. However, if the temperature is too low, the reaction rate will also slow down. Therefore, it is often necessary to start the reaction at a moderate low temperature, such as 0-5 ° C, and then gradually rise to room temperature to ensure the completion of the reaction.
After the reaction is completed, the product needs to be separated and purified. The organic solvent can be removed by reduced pressure distillation first, and then the column chromatography method is used. Silica gel is used as the stationary phase, and a suitable eluent is selected, such as the mixed solvent of petroleum ether and ethyl acetate. According to the difference in the partition coefficients of the product and the impurities in the stationary phase and the eluent, the product and the impurities are separated, and the pure 5-bromo-N-methylpyridine-2-formamide is finally obtained. Although this synthesis method is one of them, it has been verified by many chemists and is quite effective and commonly used.
