The pyridine ring is a six-membered nitrogen-containing heterocyclic ring with aromatic properties. Methylonitrile neocyanyl (-CN) is attached to the 2nd position of the pyridine ring. 4,4,5,5-tetramethyl-1,3,2-dioxyboron heterocyclopentane-2-yl, which is centered on boron atoms and forms a five-membered ring with two oxygen atoms.

It is often found in reactions that build carbon-carbon bonds, such as the Suzuki coupling reaction.

There are several common methods for the synthesis of 2-pyridyl-methylnitrile, 4- (4, 4, 5, 5-tetramethyl-1, 3, 2-dioxoboran-2-yl).
One is the Suzuki coupling reaction pathway. This reaction requires halogenated pyridyl-methylnitrile derivatives and 4, 4, 5, 5-tetramethyl-1, 3, 2-dioxoboran-2-yl borate as raw materials. First, halogenated pyridyl-methylnitrile derivatives, borate esters, bases and palladium catalysts are co-placed in suitable organic solvents. The effect of bases is to activate borate esters, making them easier to react with halogenated compounds. Palladium catalysts are the key to the reaction, promoting the fracture and recombination of carbon-boron bonds and carbon-halogen bonds. Commonly used bases, such as potassium carbonate, sodium carbonate, etc.; commonly used palladium catalysts, such as tetra (triphenylphosphine) palladium, etc. The reaction needs to be carried out under heating and inert gas protection to avoid catalyst poisoning and oxidation of raw materials and products. In this way, the coupling reaction between the two can be promoted to generate the target product 2-pyridinonitrile, 4- (4,4,5,5-tetramethyl-1,3,2-dioxaboronamyl-2-yl).
The second can be considered to be synthesized by the functional group conversion of the pyridine ring. First, a specific substituted pyridine derivative is prepared. The fourth position of the pyridine ring of this derivative needs to have a substituent that can be converted into a functional group. Then, through a series of chemical reactions, the substituent is converted into 4- (4,4,5,5-tetramethyl-1,3,2-dioxaboronyl-2-yl). For example, if the fourth position of the pyridine ring is a halogen atom, it can be reacted with magnesium to make a Grignard reagent, and then reacted with the corresponding borate ester. After a series of treatments, the target product can be obtained. In this process, the preparation of Grignard reagents requires an anhydrous and oxygen-free environment to prevent side reactions with water and oxygen.
Furthermore, the conversion of nitrile groups can also be used as an entry point. First synthesize pyridine derivatives containing 4- (4,4,5,5-tetramethyl-1,3,2-dioxaboran-2-yl), and then convert functional groups at other positions on the pyridine ring into nitrile groups through suitable reactions. If halogenated pyridine derivatives can be used to react with cyanide reagents to introduce nitrile groups, this process should pay attention to the toxicity of cyanide reagents, and the operation should be carried out in a well-ventilated environment.
