To prepare 4-cyanogen-2 - (cyanomethyl) -3,5-dimethylpyridine and its hydrochloride (1:1), the following synthesis methods can be followed.
First, use a suitable pyridine derivative as the starting material. Introduce methyl at a specific position of the pyridine ring first, which can be achieved by alkylation of the corresponding pyridine derivative with a base catalyst such as a halogenated alkane. Select an appropriate base, such as potassium carbonate, sodium carbonate, etc., in a suitable organic solvent, such as acetonitrile, N, N-dimethylformamide (DMF), heat and stir to make the reaction proceed smoothly to introduce methyl groups.
Then, try to introduce cyanyl and cyanomethyl groups. For the introduction of cyanyl groups, halogenated pyridine derivatives can be used to react with cyanide reagents, such as potassium cyanide, sodium cyanide, etc., in the presence of a phase transfer catalyst. Phase transfer catalysts such as tetrabutylammonium bromide can effectively promote the reaction at the aqueous-organic phase interface and improve the reaction efficiency. The introduction of cyanomethyl groups can first prepare compounds containing halogenated methyl groups, such as halogenated acetonitrile, and then react with pyridine derivatives, so that the cyanomethyl group can be successfully connected to a specific position in the pyridine ring under suitable conditions.
Second, another path can also be started. First, the basic skeleton containing cyanide groups and methyl groups is constructed, and then the pyrid For example, a polyfunctional nitrile compound is used as a raw material, and under acidic or basic conditions, it undergoes a condensation cyclization reaction with a suitable nitrogen-containing compound. Under acidic conditions, catalysts such as concentrated sulfuric acid and p-toluenesulfonic acid can be selected to promote the cyclization of molecules to form a pyridine ring structure, and then necessary modifications and conversions can be carried out to finally obtain the target product 4-cyanogen-2- (cyanomethyl) -3,5-dimethylpyridine and its hydrochloride (1:1).
During the synthesis process, each step of the reaction requires strict control of the reaction conditions, such as temperature, reaction time, and reactant ratio, etc., and the product is carefully separated and purified to improve the purity and yield of the product.

4-Bromo-2- (bromomethyl) -3,5-dimethylpyridine hydrochloride (1:1) There are many precautions to be paid attention to during storage and transportation.
This compound has certain chemical activity and should be stored in a dry, cool and well-ventilated place. Because it is sensitive to air and moisture, moisture can easily cause chemical reactions such as hydrolysis, which affects the quality, so strict moisture protection is required. Can be stored in sealed containers, such as glass bottles with threaded lids or sealed plastic containers, to ensure that the container is tightly sealed to prevent external moisture from invading.
In terms of temperature, it is necessary to avoid high temperature environment, which will accelerate its chemical reaction process and cause decomposition or deterioration. Generally speaking, the suitable storage temperature is 2-8 ° C. It can be stored in the refrigerated layer of ordinary refrigerators, but care should be taken to separate it from other items such as food to prevent cross-contamination.
When transporting, be sure to ensure that the packaging is firm. According to relevant transportation regulations, it needs to be classified as an appropriate dangerous product (determined according to its specific chemical properties), and corresponding warning labels should be posted. The transportation process should be smooth, avoid violent vibration and collision, and prevent the leakage of the compound due to package damage.
Since the compound contains halogen atoms such as bromine, it may be potentially harmful to the environment. If leakage occurs, it should be operated in accordance with the corresponding emergency treatment procedures in a timely manner. Small leaks can be absorbed by inert adsorbent materials (e.g. vermiculite, diatomaceous earth) and properly disposed of after collection. Large leaks require immediate evacuation of personnel, sealing off the site, and handling by professionals. Transportation and storage personnel should be professionally trained and familiar with the characteristics of the compound and emergency treatment methods to ensure safe operation and avoid accidents.
