What is the synthesis method of 3-Pyridinecarbonitrile, 2-chloro-6- (4-fluorophenyl) -?
The method of biosynthesis of 3-pyridyl-formonitrile, 2-chloro-6- (4-fluorophenyl), often follows the principle of organic synthesis. Initially, corresponding raw materials need to be prepared, such as pyridine-containing substances and halogenated aromatics with specific substituents.
Cyanyl groups can be introduced into pyridine groups at appropriate positions first, which may be achieved by reactions such as nucleophilic substitution. The activity of pyridine is established, and a suitable cyanide reagent is selected. Under suitable reaction conditions, such as temperature control, appropriate solvents and catalysts, the cyanyl group is connected to the pyridine ring to obtain a cyanophilic-containing pyridine intermediate.
Then, for the introduction of 2-chloro-6- (4-fluorophenyl), the reactivity of halogenated aromatics can be exploited. The 4-fluorophenyl halogenate and the above-mentioned pyridine intermediates are connected by coupling reaction under the action of metal catalysts such as palladium catalysts. In this process, the palladium catalyst activates the carbon-halogen bond of the halogenated aromatic hydrocarbon, so that the 4-fluorophenyl group easily binds to the specific position of the pyridine ring to form a carbon-carbon bond, and then introduces the 2-chloro-6- (4-fluorophenyl) structure.
The control of the reaction conditions is extremely critical. The temperature needs to be adjusted according to the reaction characteristics of each step. If it is too low, the reaction will be slow, and if it is too high, it will cause a cluster of side reactions. The choice of solvent should take into account the solubility of the reactants and the feasibility of the reaction, such as polar organic solvents or nucleophilic substitution. Non-polar solvents may be suitable for some coupling reactions. The amount of catalyst also needs to be accurate. If the amount is small, the catalytic effect will be poor. If the amount is large, it may increase the cost and cause other problems.
After each step of the reaction, it needs to be separated and purified to remove impurities such as unreacted raw materials and by-products. Commonly used methods include distillation, extraction, column chromatography, etc., selected according to the properties of the product and impurities, and finally obtained pure 3-pyridineformonitrile, 2-chloro-6- (4-fluorophenyl) products.
