To prepare 5-bromo-2- (bromomethyl) -1H-indolo [d] -azole, the following ancient method can be used.
The first method is to use indolo [d] -azole as the starting material. First, indolo [d] -azole is mixed in a suitable solvent, such as dichloromethane, in a low temperature environment, such as about 0 ° C, with a brominating agent, such as N-bromosuccinimide (NBS), and an initiator, such as benzoyl peroxide, is added to initiate a free radical reaction by light or heat. In this process, the bromine atom of NBS will selectively replace the hydrogen atom at a specific position of indolo [d] -azole, and the bromine atom can be introduced at a suitable position due to the electron cloud density distribution on the indole ring. If the reaction conditions are precisely controlled, such as the reaction time of about 2-3 hours, the bromine atom can be substituted at the target position to obtain the bromine-containing indolo [d] -azole derivative. After that, the derivative is reacted with halomethylating reagents, such as bromochloromethane, under alkaline conditions, such as the presence of potassium carbonate, and heated in acetonitrile solvent for several hours, about 4-6 hours. The alkaline environment prompts a nucleophilic substitution reaction at a specific position of the derivative, resulting in the introduction of bromomethyl, resulting in 5-bromo-2- (bromomethyl) -1H-indolo [d] -azole.
There are also other compounds containing indole structures as starters. For example, an indole derivative is first used to construct an indole ring through a multi-step reaction, and bromine and bromomethyl are introduced at the same time. First, the indole derivative is reacted with a suitable carbonyl compound, such as glyoxal, in the presence of an acidic catalyst, such as p-toluenesulfonic acid, in an alcohol solvent, such as ethanol, to form a Schiff base intermediate by heating. This reaction takes about 3-5 hours. Then, a nitrogen-containing nucleophile, such as an aminoalcohol, is added, and the reaction continues under the regulation of a basic environment, such as sodium carbonate, to promote the formation of the azole ring. In the process of constructing the oxazole ring, the appropriate reaction sequence and reagents can be selected, such as adding brominating reagents in the early or middle stage of the reaction, introducing bromomethylating reagents in the later stage, and gradually introducing bromide and bromomethyl at suitable positions through multiple delicate reactions. Finally, the target product 5-bromo-2- (bromomethyl) -1H-indolo [d] oxazole can be obtained. However, this multi-step reaction requires fine regulation of the reaction conditions at each step to ensure the smooth progress of the reaction and obtain high-purity products.

"Tiangong Kaiwu", the market price of 5 + -halogen-2- (halomethyl) -1H-indolo [d] -azole, depending on the situation, its price is not constant, but changes with various reasons.
First, the price of raw materials has a great impact on the city. If the production of raw materials such as halogen and halomethyl is abundant and difficult to harvest and smelt, the price will also change. If the harvest is good or the harvest is easy, the supply will be more and the price will decrease; if the harvest is poor or the harvest is difficult, the supply will be less and the price will rise. This is one end of raw materials.
Second, the cleverness of the craftsmanship is also related to its price. If there are those who are skilled in making this product, they can save materials and make it quickly in a wonderful way, and the finished product is of high quality and quantity, then the price in the market may be relatively easy. However, if the manufacturing process is not good, the quality and quantity will be inferior, and the price will increase.
Third, the demand of the city also affects the price. If the industry needs 5 + -halogen-2- (halomethyl) -1H-indolo [d] -azole, the demand is too high, and the price will rise; if the demand is thin, the supply will exceed the demand, and the price will tend to decline.
Fourth, the business plan of merchants is also one of the reasons for the price change. Whether the merchants compete for sale, stock up or not, all depend on the price. If the competition is strong, the price may drop; if the stock is large, the price may rise.
Therefore, the market price of 5 + -halogen-2- (halomethyl) -1H-indolo [d] -azole is difficult to hide. It is necessary to look at all the circumstances to know its general outline.

5-Cyanogen-2- (cyanomethyl) -1H-indolo [d] pyrimidine, which is an extremely complex chemical substance. Although it is difficult to find a direct description in the ancient sayings of Tiangong Kaiwu, it can be compared to the discussion of the characteristics of various substances in order to solve the problem of safety and toxicity of this substance.
Let's talk about safety first. This substance is not stable under general conditions due to its complex chemical structure and special groups. The existence of cyanyl groups makes its chemical activity quite high. In case of heat, open flame or contact with some specific chemical substances, it is very likely to cause violent chemical reactions, such as combustion or even explosion, just like dry wood meets fire and explodes instantly. Therefore, when storing and using, it is necessary to be in the abyss, walking on thin ice, and strictly follow specific safety procedures to prevent accidental disasters.
As for toxicity, cyanide is a highly toxic group. After entering the human body, it will quickly interfere with the respiration of cells like ghosts, causing cells to be unable to uptake and utilize oxygen normally, just like cutting off the oxygen source of life, and then causing hypoxic necrosis of tissues and organs. Inhalation of its volatile gases, skin contact or accidental ingestion can cause extremely serious damage to human health, with light dizziness, vomiting, breathing difficulties, and serious fear of life.
In short, 5-cyano-2- (cyanomethyl) -1H-indolo [d] pyrimidine is highly dangerous. Whether it is production, transportation or use, it is necessary to be careful and take comprehensive protection. Do not take it lightly to ensure safety.
