The synthesis method of 6-bromimidazolo [1,2-a] pyridine is not detailed in the classic "Tiangong Kaiwu", but it can be deduced from the chemical theory of organic synthesis today. There are two common synthesis paths.
First, 2-aminopyridine and bromoacetal diethyl acetal are used as starting materials. In a suitable solvent, such as toluene, add an appropriate amount of base, such as potassium carbonate, and heat to reflux. During this process, the amino group of 2-aminopyridine reacts with the bromine atom of bromoacetal diethyl acetal to form an intermediate. Then, under the action of heating and alkali, the intermediate undergoes intramolecular cyclization to generate 6-bromimidazolo [1,2-a] pyridine. The raw materials of this route are easy to obtain, the reaction conditions are relatively mild, but the steps are slightly complicated, and the reaction process needs to be carefully controlled.
Second, 2-halopyridine and imidazole are used as raw materials. In an organic solvent such as N, N-dimethylformamide (DMF), a metal catalyst such as a copper salt and a ligand such as 1,10-phenanthroline are added. Under heating conditions, the halogen atom of 2-halopyridine is coupled with the nitrogen atom of imidazole through metal catalysis to construct the imidazolo [1,2-a] pyridine skeleton, and the bromine atom is introduced at the 6-position. This method has high reaction efficiency and good selectivity, but the cost of catalysts and ligands is higher, and the post-reaction treatment is slightly more complicated, so the catalyst and product need to be properly separated.

6-Bromimidazolo [1,2-a] pyridine is an important intermediate in organic synthesis. During storage and transportation, many matters must be paid attention to.
It is active and easy to decompose and deteriorate when exposed to light or heat. Therefore, when storing, when placed in a cool, dry and dark place, the temperature should be controlled between 15 ° C and 25 ° C, and the humidity should not exceed 60%. Do not co-store with oxidants, acids, bases, etc., to prevent violent chemical reactions.
When transporting, also take extra care. The packaging must be tight to ensure that it is not damaged by vibration or collision during transportation. The means of transportation must be clean, dry and free of other chemical residues. During transportation, the ambient temperature and humidity should be closely monitored to avoid exposure to high temperature and humidity. In case of high temperature weather, necessary cooling measures should be taken. At the same time, transportation personnel should be familiar with the characteristics of this chemical and emergency treatment methods to prevent accidents.
In addition, whether it is storage or transportation, it is necessary to strictly follow the relevant safety regulations and operating procedures, and take corresponding protective measures, such as wearing protective gloves, goggles, etc., to ensure personnel safety and chemical stability. In this way, 6-bromimidazolo [1,2-a] pyridine can be protected during storage and transportation.
