In order to prepare 3 - (hydroxymethyl) -5 - bromo pyridino [b] indole, the method of synthesis is not detailed in ancient books, but based on today's chemical theory, the following methods can be obtained.
First, from the parent structure of pyridino [b] indole, hydroxymethyl can be introduced first. To introduce hydroxymethyl, a suitable aldehyde reagent, such as formaldehyde, can be selected under the condition of alkali catalysis. Under the condition of nucleophilic addition reaction, the specific position of pyridino [b] indole is hydroxymethylated. This process requires careful temperature control, and the reaction solvent is also required. Polar aprotic solvents such as dichloromethane or tetrahydrofuran are preferred, which can promote the smooth progress of the reaction and improve the yield of hydroxymethylation.
After obtaining 3- (hydroxymethyl) pyridino [b] indole, bromination is performed. For the bromination method, a bromination reagent such as N-bromosuccinimide (NBS) can be selected. Benzoyl peroxide (BPO) is used as the initiator, and the reaction is heated in a suitable solvent such as carbon tetrachloride under the protection of an inert gas. This reaction can selectively replace bromine atoms in the 5-position. Due to the electron cloud distribution of pyridine [b] indoles, the 5-position is relatively active and vulnerable to electrophilic attack.
Second, it can also be thought in reverse. Pyridine [b] indoles are brominated first, and NBS is also used as a brominating agent to bromide the 5-position under suitable conditions. Then hydroxymethyl is introduced. At this time, the reaction conditions for introducing hydroxymethyl are similar to the former. It is necessary to pay attention to the influence of different substituent introduction orders on the reaction activity and selectivity. In the process of introducing hydroxymethyl, due to the presence of bromine atoms, it may be necessary to fine-tune the reaction conditions, such as appropriately reducing the strength of the base to avoid affecting the bromine atoms, and strive to proceed smoothly in the reaction, and finally obtain the target product 3- (hydroxymethyl) -5-bromopyridine [b] indole.

When storing and transporting 3- (hydroxymethyl) -5-bromopyridine [b] indole, the following matters should be paid attention to:
First, in terms of storage, this compound is quite sensitive to environmental factors. It is necessary to choose a dry place, because if it is damp, it is very likely to cause chemical reactions and cause it to deteriorate. The humidity in the warehouse should be strictly controlled, and the relative humidity should not exceed 60%. And it should be placed in a cool place, away from heat sources and open flames. This compound is easily decomposed when heated, and excessive temperature may cause its chemical structure to change, thereby reducing its quality and utility. Generally speaking, the storage temperature should be maintained between 2-8 ° C, which can effectively extend its shelf life in a low temperature environment. At the same time, it needs to be stored separately from oxidants, acids, alkalis and other substances. Because of its active chemical properties, contact with these substances is likely to trigger a violent reaction and endanger safety.
Second, when it comes to transportation, ensure that the packaging is tight and stable. The packaging material must have good impact resistance and leakage resistance to prevent the package from being damaged due to collisions and bumps during transportation, causing the compound to leak. The transportation vehicle also needs to choose a suitable one. The compartment should be clean and dry, and there should be no residual substances that react with the compound. During transportation, it is necessary to strictly control the temperature to avoid large fluctuations in temperature. And pay close attention to the humidity of the transportation environment, and place desiccant in the compartment if necessary. Furthermore, when the transportation personnel are professionally trained, they are familiar with the dangerous characteristics and emergency treatment methods of this compound. In the event of an accident, they can respond quickly and properly to reduce the harm.
