The synthesis method of 6-chloro-N-cyclopropylpyridine-3-formamide is recorded in ancient books.
The first method is to start with 6-chloropyridine-3-formic acid. First, it is heated with thionyl chloride to obtain 6-chloropyridine-3-formyl chloride. This step needs to be in a well-ventilated environment, because thionyl chloride is irritating and corrosive. After that, 6-chloropyridine-3-formyl chloride is dropped into an organic solution containing cyclopropylamine, such as dichloromethane, and the temperature is controlled at a low temperature, about 0 ° C to 5 ° C, and an acid binding agent such as triethylamine is added to remove the acid generated by the reaction, and the reaction is shifted to the right. When counted, 6-chloro-N-cyclopropylpyridine-3-formamide crude product can be obtained, and then purified by column chromatography or recrystallization.
Second, 6-chloro-3-cyanopyridine is used as the starting material. It is refluxed with cyclopropylamine and a suitable catalyst, such as nickel naphthalene, in an alcoholic solvent, such as ethanol. Cyanyl is catalyzed by ammonolysis to convert into amide groups to obtain the target product. This process requires attention to the activity and dosage of the catalyst, and the reaction time needs to be controlled. If the time is insufficient, the conversion will not be complete, and if it is too long, it may cause side reactions. After the reaction is completed, the solvent is removed by distillation under reduced pressure, and then the separation method is suitable, such as silica gel column chromatography, to obtain pure 6-chloro-N-cyclopropylpyridine-3-formamide.
There are also pyridine derivatives as raw materials, obtained by a series of reactions such as halogenation and amination. First, chlorine atoms are introduced into the specific position of the pyridine ring by halogenation, and then cyclopropyl is introduced by amination to construct the amide structure. There are many steps in this way, and the control of the reaction conditions of each step and the purification of the intermediate product need to be fine in order to obtain 6-chloro-N-cyclopropylpyridine-3-formamide with high yield and high purity.

6-Chloro-N-cyclopropylpyridine-3-formamide, this is an organic compound. Looking at its physical properties, it is mostly solid at room temperature. Due to the strong intermolecular forces, the molecules are closely arranged.
When it comes to the melting point, the melting point of this compound is quite high. Because there are various forces in the molecule, such as the conjugated system of the pyridine ring, the space effect of the chlorine atom and the cyclopropyl group, all of which enhance the intermolecular interaction and stabilize the lattice structure. More energy is required to destroy, so the melting point is very high.
Its solubility is quite special. In water, the solubility is poor. Because its molecular polarity is weak, and water is a strong polar solvent, according to the principle of "similarity and miscibility", the polarity difference is large, making it difficult for the two to dissolve each other. However, in organic solvents, such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), the solubility is still good. The polarity of organic solvents is similar to that of 6-chloro-N-cyclopropylpyridine-3-formamide, and appropriate interactions can be formed between molecules, such as van der Waals force, dipole-dipole interaction, etc., to promote its dissolution.
The appearance of this compound is usually white or off-white crystalline powder. This appearance is related to its crystal structure. The crystals are arranged regularly and the light is reflected uniformly, so it presents such color and shape.
Furthermore, its stability cannot be ignored. Under general environmental conditions, it has certain stability. When encountering strong oxidizing agents, strong acids or strong bases, the chemically active parts, such as pyridine rings and amide groups, are prone to chemical reactions, resulting in structural changes.
The physical properties of 6-chloro-N-cyclopropylpyridine-3-formamide are affected by various groups in the molecular structure, which are of great significance for its storage, transportation and application in chemical reactions.

6-Chloro-N-cyclopropylpyridine-3-formamide, this substance is on the market, and its price is uncertain, due to various reasons. Looking at the price of various substances in the past, it is all affected by various factors, and the same is true.
The first to bear the brunt is the price of raw materials. If the raw material for synthesizing this amide is synthesized, the difficulty of obtaining and preparing it is related to the cost. If the raw material is rare or cumbersome to prepare, the cost of producing this substance will be high, and its price in the market will also rise. Conversely, if the raw material is easy to obtain and the price is flat, the cost will decrease and the price will also decrease.
Second, the technique of production is also the main reason. Sophisticated techniques can increase the rate of production, reduce energy consumption and waste, resulting in lower costs and better prices. If the technique is poor, the output is less and the consumption is more, the price will be high.
Furthermore, the supply and demand of the market are also heavy. If there are many people who need it, and the production is insufficient, the price will rise. If the supply exceeds the demand, the business will sell the goods, or reduce the price to attract customers.
In addition, regulation and taxation also have an impact. Strict regulation increases the cost of production and the price is also high. Changes in taxation can also make prices rise and fall.
However, after checking the past market conditions, it is difficult to determine the exact price. Or at some times and places, due to all the advantages, the price is slightly easier; or due to difficult conditions, the price suddenly jumps. Therefore, in order to know the current market price, it is necessary to carefully observe the market of chemical materials and consult suppliers and operators to obtain a near-real price.
