To prepare 1 - (2,2,2 - trichloroethyl) - 1,2,3,6 - tetrahydropyridine - 4 - carboxylic acid ester, there are many ways to synthesize it, and now I will come to you one by one.
First, it can be converted from a specific starting material by the delicate transformation of organic reactions. First, take a compound containing a specific functional group, under suitable reaction conditions, such as in the catalysis of a certain catalyst, and control the temperature and reaction time to make it undergo nucleophilic substitution reaction. In this process, the atoms or groups of the reactant molecules are transposed with each other, gradually building the basic structure of the target product. Then, after a series of modification reactions, such as esterification reaction, in a specific esterification reagent and catalytic environment, the specific carboxylic group and alcohol group in the molecule are esterified, so that the required carboxylic acid ester group is added to achieve the synthesis of the target product.
Second, another approach can also be adopted. Starting from a different starting material, the molecule is formed into a pyridine ring structure by means of a cyclization reaction. This cyclization reaction may require a specific reaction medium and accelerator to promote the atoms in the molecule to connect with each other to form a ring. After cyclization, the reaction of introducing chlorinated groups is carefully controlled to check the reaction point and the degree of substitution to achieve the introduction of 2,2,2-trichloroethyl. Finally, the formation of 4-carboxylic acid esters is achieved through the transformation of functional groups at specific positions on the pyridine ring. Each step of the reaction requires careful regulation of the reaction conditions to obtain it smoothly.
Third, the target product can be disassembled into simpler fragments according to the concept of reverse synthesis analysis. These fragments are synthesized separately first, and then the fragments are cleverly connected by means such as coupling reactions. In the coupling reaction, the appropriate coupling reagents and reaction conditions need to be selected to ensure precise docking between fragments, and gradually converge into complete target product molecules. Although the steps of this synthesis method may be slightly complicated, it is more accurate to control the reaction check point, which can effectively improve the yield and purity of the synthesis.
All these synthesis methods have their own advantages and disadvantages. In actual operation, it is necessary to carefully choose the optimal synthesis path according to the availability of raw materials, the difficulty of the reaction, the consideration of cost, and the purity requirements of the target product.

1 - (2,2,2 -triethylamino) -1,2,3,6 -tetrahydropyridine-4 -carboxylate ethyl ester is an organic compound. Its physical and chemical properties are as follows:
In terms of appearance properties, it is often colorless to light yellow liquid, and under certain conditions, it may change slightly in color due to impurities and other factors.
In terms of solubility, it is soluble in common organic solvents, such as ethanol, ether, dichloromethane, etc. This property is derived from the interaction force between its molecular structure and organic solvents. For example, the organic groups it contains can form van der Waals force or hydrogen bonds with organic solvent molecules, thereby enhancing solubility.
Boiling point and melting point. The boiling point will be affected by the intermolecular force. Due to the existence of a certain van der Waals force and hydrogen bonding between the molecules of the compound, the boiling point is in a specific range; the melting point is also determined by the molecular arrangement and interaction. In the crystalline state, the molecules are closely arranged, and a specific energy is required to destroy the lattice, so there is a specific melting point.
In terms of stability, it is relatively stable under normal conditions, but in case of extreme conditions such as strong acid, strong base or high temperature, the molecular structure may change. In case of strong acid, the ester group in it may undergo hydrolysis reaction to generate corresponding acids and alcohols; in case of strong base, similar reactions may also be triggered, and the reaction mechanism involves processes such as nucleophilic substitution.
The reaction activity is higher, due to the presence of double bonds, ester groups and other functional groups in the molecule. Double bonds can undergo addition reactions, such as addition to hydrogen halides, following the Markov rule; ester groups can participate in reactions such as hydrolysis and alcoholysis, and are widely used in the field of organic synthesis. They can be used as intermediates to construct more complex molecular structures.

I think your question is about (2,2,2-triethylamino) -1,2,3,6-tetrahydropyridine-4-ketoate in the market price range. However, this is not an easy question to answer. Due to changes in market conditions, the price also fluctuates, and it is affected by many factors.
According to the method of "Tiangong Kaiwu", the price of such materials may involve the abundance of their raw materials, the difficulty of preparation, and the amount of demand. If the raw materials are widely distributed, easy to collect and convenient to produce, and the supply exceeds the demand, the price may be lower. On the contrary, if the raw materials are rare and expensive, the production is complicated, and the demand is numerous, the supply will exceed the demand, and the price will increase.
However, I do not have the details of the real-time market conditions, and it is difficult to determine the range of its price. If you want to know the details, you can get a more accurate price range by visiting various pharmaceutical shops, chemical companies, or looking up the records of market conditions. Or consult people who are familiar with the market of chemical materials.

4-Ethyl caseate should be stored in a cool and well-ventilated place. Avoid exposure to fire and heat sources in the vicinity to prevent danger. Because of its flammability, it is easy to burn in case of open flames and hot topics.
And it needs to be stored separately from oxidants, acids, etc., and must not be mixed. Because of its active chemical properties, it may be co-stored with other chemicals, or chemical reactions may occur, causing danger.
Furthermore, the storage area should be equipped with suitable materials to contain possible leaks. In this way, if there is a leak, it can be dealt with in time to reduce the damage. The packaging should also be well sealed to prevent volatilization and deterioration in contact with air. After use, be sure to properly seal the packaging and store it in the specified place to ensure safety.
