The common synthesis methods of pseudo- (4-cyanobenzyl) pyridine-2-formamide are various, and today they are described in ancient Chinese.
First, cyanobenzyl is used as the beginning, and the hydrogen of the benzyl group is halogenated to be replaced by a halogen atom. After halogenation, it reacts with pyridine-2-formamide under the catalysis of a base. This product can be obtained by combining the two with a base, such as potassium carbonate and sodium carbonate, in a suitable solvent, such as N, N-dimethylformamide, dimethylsulfoxide, etc., at a suitable temperature, or in the state of heating and reflux. The reaction mechanism is that the halogen atom of halogenated benzyl is quite active, and it is easy to be attacked by the nucleophilic group of pyridine-2-formamide, so as to form bonds.
Second, pyridine-2-formyl chloride can be reacted with amine compounds containing cyanobenzyl. First, pyridine-2-formyl chloride is prepared, and pyridine-2-formyl acid is reacted with chlorinated reagents such as thionyl chloride and phosphorus oxychloride. Then, pyridine-2-formyl chloride and cyanobenzyl-containing amine react slowly in inert solvents such as dichloromethane and chloroform at low temperature. Among them, the carbonyl group of the acid chloride is active, and the nitrogen atom of the amine is nucleophilic. The combination of the two, the hydrogen chloride is removed, and the target product is obtained.
Third, the coupling reaction catalyzed by transition metals is used. For example, in a palladium catalytic system, select suitable palladium catalysts, such as palladium acetate, tetra (triphenylphosphine) palladium, etc., with suitable ligands, such as tri-tert-butylphosphine, bipyridine and the like. Coupling with pyridine-2-formamide derivatives containing cyanobenzyl halide or borate in a base and a suitable solvent. This method requires precise control of reaction conditions, temperature, catalyst dosage, ligand ratio, etc. are all related to the success or failure of the reaction and the yield. Its advantage is that the reaction selectivity is good, and the carbon-nitrogen bond can be effectively constructed to obtain the desired pseudo- (4-cyanobenzyl) pyridine-2-formamide.

(What is the market price of pseudo- (4-cyanobenzyl) pyridine-2-formate ethyl ester?)
The market price of (4-cyanobenzyl) pyridine-2-formate ethyl ester is the key to commercial trade and industrial circulation. However, its price is not constant and often fluctuates with many factors.
First, the trend of supply and demand affects its price. If the market is above, the demand for this compound is strong, and the supply is limited, just like the rain in a drought, the price will rise. On the contrary, if the supply exceeds the demand, such as flooding, the price will be at risk of falling.
Second, the price of raw materials is also a major factor. If the price of all raw materials required for the preparation of (4-cyanobenzyl) pyridine-2-ethyl formate rises, such as chai rice is more expensive than in the past, the cost of this compound will increase, and the merchant will increase the price in order to ensure profitability.
Third, changes in the current situation and policy changes also have an impact. War chaos, traffic blockage, poor logistics, or policy regulation and production restrictions can all cause price volatility.
Fourth, technological innovation and process improvement, if production efficiency can be improved and costs reduced, such as skilled craftsmen making good use of new devices, prices may also be reduced.
As for the current specific price, it is difficult to say exactly because there is no real-time market information. If you want to know the details, you can consult the chemical raw material trading market, related industry guilds, or professional business information platforms, where there should be more accurate price quotations.

(What are the storage conditions of pseudo- (4-cyanobenzyl) pyridine-2-formamide? Please simulate "Tiangong Kaiwu" to answer this question in classical Chinese format, about 500 words, direct text, no title and conclusion.)
If you want to store pseudo- (4-cyanobenzyl) pyridine-2-formamide well, you should study its properties in detail and go with the flow. Although this materiality is not explicitly stated in ancient scrolls, it can be roughly deduced from today's reasons.
The first weight avoids moisture. Cover water vapor is easy to invade various substances and cause deterioration and decay. Therefore, when storing this amide, it is advisable to choose a place with high dryness, not near water or wetlands. If it is in a humid place, water vapor gradually seeps, or causes it to hydrolyze, destroying its essence and losing its use. It is like a house leaking and wet millet, and the millet will be moldy and rotten, and it cannot be eaten.
Times need to be protected from light. Light, a kind of energy, or the structure of a cataclysmic substance. If this amide is exposed to light for a long time, it may cause photochemical reactions, causing its chemical properties to change. If the silk is exposed to the hot sun, the silk color is easy to darken, and the quality is easy to be brittle, all of which are harmful to light. It is necessary to cover it with something that blocks light, or hide it in a dark room, and enter without light.
Furthermore, temperature is also If it is overheated, the molecular activity will increase greatly, and the reaction will be easy to produce; if it is too cold, it may cause its crystalline morphology to change, which will also damage its properties. It is advisable to find a cool place with moderate temperature, so that this amide can exist safely. Just like a person in a suitable place for cold and heat, the body is healthy and healthy, and the same is true for things. If it is suitable for temperature, it will be stable.
And it should be prevented from mixing with other things. Different substances have different properties, and miscellaneous parts may react. This amide is stored alone and does not combine with acids, bases, strong oxidants, etc. If different drugs are co-placed in one container, changes will occur, and the drug resistance will be obedient.
In summary, the storage of pseudo- (4-cyanobenzyl) pyridine-2-formamide should be in a dry, dark, cool place, and not mixed with other things, so that its quality can be preserved for future use.
