The synthesis method of 6-bromo-1,2,3,4-tetrahydroisoquinoline hydrochloride covers many kinds. In the past, or from a substrate with a corresponding structure, through halogenation reaction, bromine atoms are introduced, and then cyclization is formed, and the reaction with hydrochloric acid is repeated to obtain this product. The halogenation method, or the use of brominating agents, such as liquid bromine, N-bromosuccinimide, etc., is selected according to the activity of the substrate and the reaction conditions. The step of cyclization, or the mechanism of intracolecular nucleophilic substitution, etc., to construct the isoquinoline ring system.
There are other synthesizers, or first prepare 1, 2, 3, 4-tetrahydroisoquinoline, and then brominate, and then form hydrochloride. At the time of bromination, the check point and degree of the reaction need to be controlled, which can be adjusted by factors such as catalysts and solvents. For example, in a specific solvent, a suitable catalyst is used to catalyze, so that the bromine atom precisely falls into the 6 position.
In addition, there are also simple raw materials, through multi-step reactions, to gradually build the target molecular structure. The key intermediate is first synthesized, followed by a series of reactions such as functional group conversion and cyclization, and finally 6-bromo-1, 2, 3, 4-tetrahydroisoquinoline is obtained, which is complex with hydrochloric acid to form a salt.
