To prepare 4% 2C5% 2C6% 2C7-tetrahydro-3H-indolo [4% 2C5-c] pyridine and its hydrochloride, the following ancient methods can be used.
First, a suitable starting material is taken, usually a nitrogen-containing heterocyclic compound and an olefin or alkyne with a specific structure. Take a nitrogen-containing aromatic heterocycle and an alkenyl halide as an example. In a suitable reactor, an appropriate amount of base, such as potassium carbonate or sodium carbonate, is added to provide an alkaline environment to promote the nucleophilic substitution reaction. The solvent used should be a polar aprotic solvent, such as N, N-dimethylformamide (DMF) or dimethyl sulfoxide (DMSO), which can effectively dissolve the reactants and is beneficial to the reaction process. Heat up to a certain temperature, usually 80-120 ° C, stir for several hours, so that the two can fully react to form a preliminary intermediate, which contains a linked carbon-nitrogen bond.
Then, the intermediate is reduced to obtain the target 4% 2C5% 2C6% 2C7-tetrahydro-3H-indolo [4% 2C5-c] pyridine. Optional reducing agent, such as sodium borohydride or lithium aluminum hydride. If sodium borohydride is used, it is often reacted in alcoholic solvents such as methanol or ethanol, and the conditions are relatively mild. Lithium aluminum hydride needs to be operated in anhydrous ether solvents, such as anhydrous tetrahydrofuran, because its activity is very high. Control the reaction temperature, in an ice bath or room temperature, depending on the specific situation, and the number of reactions, in order to achieve the purpose of sufficient reduction.
To obtain 4% 2C5% 2C6% 2C7-tetrahydro-3H-indolo [4% 2C5-c] pyridine hydrochloride, the product obtained above can be placed in an appropriate amount of organic solvent, such as dichloromethane or ethyl ether, into dry hydrogen chloride gas, or dropwise in an alcoholic solution of concentrated hydrochloric acid. In this process, the reaction phenomenon needs to be closely observed, until the reaction system no longer absorbs hydrogen chloride gas, or the pH value of the solution is constant, indicating that the reaction has reached the end point. Finally, through separation and purification methods, such as recrystallization or column chromatography, pure 4% 2C5% 2C6% 2C7-tetrahydro-3H-indolo [4% 2C5-c] pyridine hydrochloride can be obtained.

Wen Jun inquired about the market price of 4% 2C5% 2C6% 2C7-tetrahydro-3H-indolo [4,5-c] pyridine and its salts. The price of these things in the market often varies due to a variety of factors.
First, the purity of the material is extremely critical. If the purity is high and there are few impurities, the price will be high; if the purity is not high and there are more impurities, the price may be slightly lower. Second, the supply and demand situation in the market also affects the price. If there are many demands, and there are few supplies, the price will rise; conversely, if the supply exceeds the demand, the price may fall. Third, the process of making this thing is simple, which is also related to the price. The process is complicated, labor-intensive and time-consuming, the cost must be high, and the price will follow; if the process is relatively simple, the cost may be low, and the price may also drop.
And these chemical substances may have different prices due to different uses. For scientific researchers, the requirements for purity are quite high, and the price is often not low; if it is used in non-extremely precise places such as industrial mass production, the requirements for purity are slightly reduced, and the price may vary. However, the specific price is difficult to determine. It is necessary to carefully check the quotations of various suppliers in the market, or consult the professional brokerage of chemical materials, in order to obtain a more accurate market price. And the chemical market is changing, and the price is also changing at any time. Therefore, if you want to know the real-time price, you must inquire carefully, so as not to be wrong.

4% 2C5% 2C6% 2C7-tetrahydro-3H-pyrrolido [4,5-c] pyridine and its hydrochloride need to pay attention to many matters during storage and transportation.
This compound and its hydrochloride are mostly products of chemical synthesis, with specific chemical activities and physical properties. When storing, the first environment is dry. Because it may be sensitive to water vapor, moisture can easily cause chemical reactions, affecting quality and purity. It should be placed in a dry and ventilated place and contained in a sealed container, such as a glass bottle or plastic bottle with good sealing performance, to prevent moisture from invading.
Temperature control is also critical. Usually it needs to be stored in a cool environment to avoid high temperature. High temperature may cause the compound to decompose, deteriorate, or accelerate the rate of chemical reaction, changing its chemical structure and properties. Generally, it is recommended to store the refrigeration conditions at a temperature of 2-8 ° C, which is determined according to the characteristics of the compound and relevant standards.
Storage must also be protected from light. Some of these compounds are sensitive to light, and light or luminescent chemical reactions reduce quality. They should be stored in opaque containers or placed in a dark place.
When transporting, the packaging must be stable. Use shock-proof and collision-proof materials, such as foam, cotton, etc., to ensure that the compounds are not damaged by impact during transportation bumps.
The environment of the transportation vehicle also needs to be considered. Ensure that the transportation environment is dry and the temperature is suitable. Avoid mixing with other chemicals to prevent mutual reaction. Transportation personnel should receive professional training and be familiar with the characteristics of the compound and emergency treatment methods. In case of emergencies such as leakage during transportation, they can respond quickly and correctly to ensure the safety of personnel and the environment from pollution.
