The method of synthesizing α-phenylpyridine-2-acetamide has been explored by ancient chemists, and the methods are various, and the following are a few.
One is to use pyridine-2-acetic acid as a base to perform condensation with aniline derivatives. First take pyridine-2-acetic acid, in a suitable solvent, such as dichloromethane, N, N-dimethylformamide, etc., add a condensing agent, such as dicyclohexyl carbodiimide (DCC), or 1- (3-dimethylaminopropyl) - 3-ethyl carbodiimide hydrochloride (EDC · HCl), and re-add the catalyst 4-dimethylaminopyridine (DMAP) to promote the reaction speed. After the system is mixed well, slowly add the aniline derivative, control the temperature in an appropriate range, or room temperature, or heat reflux, depending on the reactant activity. After reaction, the process was observed by thin-layer chromatography (TLC). When the raw materials were exhausted, the main product was formed, and post-treatment was carried out. After solvent extraction, refining by column chromatography or recrystallization, α-phenylpyridine-2-acetamide can be obtained.
Second, start from pyridine-2-acetonitrile. First, pyridine-2-acetonitrile is hydrolyzed to pyridine-2-acetic acid. This step can be catalyzed by acid or base. Sulfuric acid, hydrochloric acid and the like are commonly used in acid catalysis, and sodium hydroxide and potassium hydroxide are used in alkali catalysis. After hydrolysis, it is condensed with aniline derivatives as before. Or pyridine-2-acetonitrile is first reacted with phenylmagnesium halide to obtain α-phenylpyridine-2-ethanol derivatives, which are oxidized to acid and then condensed with amines to obtain the target product.
Third, 2-halopyridine and phenylacetamide derivatives are used as raw materials. In the presence of appropriate bases, such as potassium carbonate and sodium carbonate, in organic solvents, such as toluene and acetonitrile, the reaction is heated. Metal catalysts such as copper salts and palladium salts can be added to facilitate the aromatization of halopyridine, so that the two are coupled to form α-phenylpyridine-2-acetamide. After the reaction, follow the conventional post-processing method to purify the product.
All synthesis methods have their own advantages and disadvantages. Fang Jia should choose them carefully according to various factors such as the availability of raw materials, the cost, and the difficulty of reaction, in order to achieve the best synthesis effect.

Alpha-phenylpyridine-2-acetamide is a kind of organic compound. During storage and transportation, there are several important items to be paid attention to.
First words storage, this compound should be placed in a cool, dry and well ventilated place. Cover because of its nature or affected by temperature and humidity, if it is in a high temperature and humid place, it may deteriorate. For example, in summer heat, if the storage environment is poor, it is easy to change its chemical structure and damage its quality. The storage place should also be away from fire and heat sources to prevent the risk of fire. Because of its flammability, it is dangerous to encounter open flames and hot topics.
Furthermore, it needs to be stored separately from oxidants, acids, bases, etc., and must not be mixed. This is because alpha-phenylpyridine-2-acetamide is chemically active, and it is easy to cause chemical reactions when it encounters such substances, or cause explosions, fires and other disasters.
As for transportation, the transportation vehicle must be clean and free of impurities such as combustibles and oxidizers. During transportation, the driving should be stable, prevent bumps and vibrations, and avoid leakage caused by package damage. And the transportation personnel must be familiar with its physical and chemical properties and emergency response methods. In case of leakage, they can take appropriate measures quickly.
Also, packaging is also very important. Appropriate packaging materials must be used to ensure tight packaging to ensure no leakage during transportation and storage. The packaging label should be clear, indicating the name of the substance, hazard characteristics, emergency treatment methods, etc., so that relevant personnel can know how to deal with it.
