The Synthetic Routes of 3-(4-BROMOPHENYL)PYRIDINE

3-(4-Bromophenyl)pyridine is a commonly used synthetic intermediate in the chemical industry.
It is used in the production of various chemicals, pharmaceuticals, and materials.
The synthetic routes of 3-(4-bromophenyl)pyridine can be broadly classified into two categories: classical synthesis routes and modern synthesis routes.

Classical Synthesis Routes of 3-(4-Bromophenyl)Pyridine

One of the classical synthesis routes of 3-(4-bromophenyl)pyridine involves the reaction of 4-bromophenyl amide with pyridine in the presence of a strong acid catalyst such as sulfuric acid.
The reaction results in the formation of 3-(4-bromophenyl)pyridine.
This route is relatively simple and cost-effective, but it involves the use of hazardous chemicals and requires careful handling and storage.

Another classical synthesis route involves the reaction of 4-bromophenyl chloride with pyridine in the presence of a Lewis acid catalyst such as aluminum chloride.
The reaction produces 3-(4-bromophenyl)pyridine as a precipitate.
This route is also relatively simple and cost-effective, but it requires careful handling and storage of the Lewis acid catalyst.

Modern Synthesis Routes of 3-(4-Bromophenyl)Pyridine

Modern synthesis routes of 3-(4-bromophenyl)pyridine are more complex and require the use of specialized equipment and reagents.
One modern route involves the reaction of 4-bromophenylamine with 3-pyridylboronic acid in the presence of a palladium catalyst.
This reaction producing 3-(4-bromophenyl)pyridine.
This route is more efficient and less hazardous than classical routes, but it requires specialized equipment and reagents.

Another modern route involves the reaction of 4-bromophenyl acetate with a reagent such as sodium hydride in the presence of a solvent such as DMF.
The reaction produces 3-(4-bromophenyl)pyridine as a precipitate.
This route is also more efficient and less hazardous than classical routes, but it requires specialized equipment and reagents.
