To prepare 5-% Jiang-1H-benzoindole, the method is as follows:
First, it can be started with o-nitrotoluene and ethyl chloroacetate, and then condensed to obtain ethyl o-nitrophenylacetate. This step needs to be carried out in a suitable solvent under alkali catalysis to make the two effectively combine. Then the ethyl o-nitrophenylacetate is reduced to obtain ethyl o-aminophenylacetate, a commonly used reducing agent such as iron and hydrochloric acid. Next, it undergoes a cyclization reaction, which can be heated under acidic conditions to promote its intramolecular cyclization, and then the 5-% Jiang-1H-benzoindole precursor can be obtained. After appropriate modification and purification, the target product can be obtained.
Second, o-haloaniline and acrylate are used as raw materials. First, the addition reaction between o-haloaniline and acrylate occurs under the action of alkali and catalyst to form a carbon-nitrogen bond. This reaction condition needs to be precisely controlled to ensure the direction and yield of the reaction. Then the molecule is cyclized, and the intracellular ring formation is induced by changing the reaction temperature, pH and other conditions. After cyclization, the product is separated and purified, and impurities are removed to obtain a high-purity 5-% Jiang-1H-benzoindole.
Third, phenylhydrazine and cyclohexanone are used as the starting materials. The two first condensate to form phenylhydrazone, and this reaction can occur under the appropriate catalyst and temperature. Under the influence of specific reagents and conditions, the molecular structure is rearranged and aromatized into 5-% Jiang-1H-benzoindole. After the reaction, the product is purified by extraction, distillation, crystallization and other means to obtain a pure 5-% Jiang-1H-benzoindole.

It is difficult to determine the price range of 5-% Jiang-1H-indacarbazole in the market. Covering this product may involve rarity, and its price often varies depending on the quality, the supply and demand of the market, and the complexity and simplicity of the system.
If the quality is pure and refined, the supply is less than the demand, and the production process is complicated, time-consuming and expensive, the price will be high, or up to thousands of gold. However, if the quality is inferior, and the market supply is abundant, the system is not difficult, the required fee is also small, and the price may not exceed 100 gold.
And its application field is also related to the price. If it is an indispensable material in the field of high-tech, the price will also rise due to its heavy use. On the contrary, if the application is limited and it is only an ordinary material, the price will be difficult to be high.
Therefore, in order to determine the price of 5-% Jiang-1H-indacarbazole, it is necessary to consider many factors such as quality, supply, demand, use and control in order to obtain a more accurate price range. However, it is difficult to determine its specific price geometry.
