The synthesis method of 4-methylpyridine-2-formonitrile has been explored by many ancient people, and it is described by you today.
First, 4-methylpyridine can be prepared by cyanidation with 4-methylpyridine as the starting material. In a suitable reaction vessel, 4-methylpyridine is placed in a specific solvent, such as dimethylformamide (DMF), which can fully disperse the reactants and facilitate the reaction. Then add cyanide reagents, such as potassium cyanide (KCN) or trimethylsilyl cyanide (TMSCN). The reaction needs to be carried out under certain temperature and pressure conditions, usually between 80 and 120 degrees Celsius. This temperature range allows the reaction rate to be moderate, neither too fast to increase side reactions nor too slow to take too long. At the same time, applying a certain pressure, about 1-3 atm, can promote the positive progress of the reaction. Under these conditions, the cyanyl group replaces the hydrogen atom at a specific position on the pyridine ring, and then 4-methylpyridine-2-formonitrile is obtained.
Second, react with the cyanide reagent with 2-halo-4-methylpyridine. First, 2-halo-4-methylpyridine (the halogen atom can be chlorine, bromine, etc.) is placed in a suitable organic solvent, such as acetonitrile, together with an appropriate amount of alkali, such as potassium carbonate. The function of the base is to neutralize the halogenated hydrogen generated by the reaction and push the reaction to the right. Then a cyanide reagent, such as sodium cyanide (NaCN), is added. The reaction temperature should be controlled at 60-100 ° C. The reaction lasts for several hours, and the halogen atom is replaced by a cyanyl group. After the product is separated and purified, pure 4-methylpyridine-2-formonitrile can be obtained.
Third, it is synthesized by the cyclization reaction of pyrid The pyridine ring was formed by a multi-step reaction with a chain compound containing an appropriate substituent as the starting material, and methyl and cyanyl groups were introduced at the same time. The steps of this method are slightly complicated, and the reaction conditions of each step need to be precisely controlled, including the proportion of reactants, reaction temperature, reaction time, etc., in order to obtain the target product 4-methylpyridine-2-formonitrile.
These several synthesis methods have their own advantages and disadvantages. According to actual needs, factors such as the availability of raw materials, cost, and difficulty of reaction conditions must be weighed, and the good one should be selected.

4-Methylpyridine-2-formonitrile is also an organic compound. During storage and transportation, many matters must be paid attention to.
First words storage, this compound should be stored in a cool, dry and well-ventilated place. Cover because of its sensitivity to heat, moisture, high temperature and humidity, it may cause its properties to change, or even cause chemical reactions. Furthermore, it must be kept away from oxidants, acids, bases and other substances to avoid interaction and accidental changes. Because of its certain chemical activity, improper contact with other substances, or violent reaction, risk of explosion. The storage place should also be clearly marked to make the user clear about its nature and precautions.
As for transportation, caution is also required. The transportation container must be solid and sealed to prevent leakage. During handling, it should not be loaded and unloaded brutally, and it should be handled with care to avoid damage to the container. Transportation vehicles should also ensure that there is no fire source, heat source, and good ventilation equipment. Transportation personnel must be professionally trained to be familiar with the characteristics of this object and emergency treatment methods. In the event of leakage and other accidents, they can be disposed of quickly and properly. If there is a leak during transportation, the surrounding people should be evacuated immediately, the scene should be isolated, and corresponding measures should be taken to clean it up according to its chemical characteristics. Do not take it lightly.
