The synthesis method of 2-bromo-6-pyridyl formaldehyde has been known for a long time. In the past, the wise man, in the field of organic synthesis, worked hard to find a good recipe for the preparation of this compound.
One method is to use pyridine as the base and obtain it through modification. First, under specific reaction conditions, pyridine is brominated with a suitable brominating agent, such as bromine or N-bromosuccinimide (NBS). This bromination step requires the selection of appropriate solvents, such as dichloromethane, carbon tetrachloride, etc., and the temperature and reaction time are controlled, so that bromine atoms can be accurately introduced into the 2-position of the pyridine ring. Next, the aldehyde group is introduced into the 6-position of the pyridine ring. This can be achieved by the Vilsmeier-Haack reaction. The Vilsmeier reagent is prepared with N, N-dimethylformamide (DMF) and phosphorus oxychloride (POCl). It is co-heated with brominated pyridine derivatives to successfully connect the aldehyde group to the 6-position. In this process, the reaction temperature and the proportion of reagents are all related to success or failure, and caution is required.
There is another way, using 2-bromo-6-methylpyridine as the starting material. The methyl group is first oxidized to an aldehyde group. This oxidation method can be used with a mild oxidizing agent, such as a mixed system of manganese dioxide and sulfuric acid, or active manganese dioxide, at an appropriate temperature and in a solvent, so that the methyl group is gradually converted into an aldehyde group, and then 2-bromo-6-pyridine formaldehyde is obtained.
Furthermore, starting from a suitable pyridine derivative, a metal-catalyzed coupling reaction can be used to introduce bromine atoms first, and then aldehyde groups elsewhere. For example, in a palladium-catalyzed reaction, a suitable palladium catalyst and ligand are selected to couple the bromine-containing reagent with the pyridine derivative, and then an aldehyde group is introduced through subsequent steps. This path is also a good way for synthesis. All methods have their own advantages and disadvantages, and they must be weighed and used according to the actual situation.
