To prepare 2-bromo-N, N-dimethylpyridine-4-amine, the following ancient method can be used.
The starting material is 4-aminopyridine. First, 4-aminopyridine is reacted with a halogenated hydrocarbon, such as iodomethane or dimethyl sulfate, in a suitable solvent, such as acetone or acetonitrile, and a suitable base, such as potassium carbonate or sodium carbonate, is added. Heat reflux to obtain N, N-dimethyl-4-aminopyridine. This step aims to modify the amino group with N-methylation.
After obtaining N, N-dimethyl-4-aminopyridine, bromide with brominating reagents. Commonly used brominating reagents such as liquid bromine and N-bromosuccinimide (NBS). If liquid bromine is used, liquid bromine can be slowly added dropwise in an inert solvent such as dichloromethane or carbon tetrachloride at a low temperature, such as 0 ° C to room temperature, and the reaction proceeds smoothly. If NBS, benzoyl peroxide, etc. are used as initiators, and heated and refluxed in an appropriate solvent, such as carbon tetrachloride, the 4-position of the pyridine ring can be successfully brominated to obtain 2-bromo-N, N-dimethylpyridine-4-amine.
Another way can start from pyridine. Pyridine is first nitrified, and concentrated nitric acid and concentrated sulfuric acid are mixed as nitrifying reagents. Control the reaction temperature to obtain nitropyridine. After reduction, such as catalytic reduction with iron powder and hydrochloric acid, or hydrogen and palladium carbon, aminopyridine is obtained. The subsequent steps are as above, N-methylation first, and re-bromination, and the target product can also be obtained. When
is prepared, attention should be paid to the fine regulation of reaction conditions, accurate measurement of raw materials and reagents, and proper separation and purification after each step of reaction, in order to obtain high purity 2-bromo-N, N-dimethylpyridine-4-amine.
