    What is the synthesis method of N-Methyl-1,2,3, 4-tetrahydroisoquinoline?
    The synthesis method of N-methyl-1,2,3,4-tetrahydroisoquinoline has been around for a long time and has been new for a long time. Its methods are multi-ended and each has its own ingenuity. This is a detailed description for you today.
    First, it can be prepared by the reaction of phenethylamine and formaldehyde by Pictet-Spengler. This is a classic method and has been used by the world for a long time. Phenethylamine and formaldehyde are placed in a suitable solvent, and an acid catalyst is added, often protonic acids, such as hydrochloric acid and sulfuric acid, are heated to the appropriate temperature, and the reaction starts. In the meantime, the amino group of phenethylamine and the carbonyl group of formaldehyde are condensed to form an imine intermediate, which is then cyclized to obtain N-methyl-1,2,3,4-tetrahydroisoquinoline. In this process, temperature, solvent and catalyst dosage are all key, and there is a slight difference in the pool, or the yield fluctuates, and the product is impure.
    Second, isoquinoline is used as the starting material, and it is obtained through two steps of reduction and methylation. First, the double bond of isoquinoline is reduced with appropriate reducing agents, such as sodium borohydride, lithium aluminum hydride, etc., to obtain 1,2,3,4-tetrahydroisoquinoline. After methylating reagents, such as iodomethane, dimethyl sulfate, etc., under basic conditions, the nitrogen atom is methylated to obtain the target product. Although this path is slightly complicated, the reaction conditions of each step are clear, and the product is easy to separate and purify.
    Third, benzyl halide and ethylamine derivatives are used as raw materials to prepare through multi-step reaction. First, the benzyl halide and ethylamine derivatives undergo nucleophilic substitution reaction to obtain the corresponding amine compound. Then through cyclization, reduction and other steps, the tetrahydroisoquinoline skeleton is gradually constructed, and finally N-methyl-1,2,3,4-tetrahydroisoquinoline is methylated. This approach requires fine planning of the reaction sequence and conditions, but can be flexibly adjusted according to the convenience of raw materials.
    All synthesis methods have their own advantages and disadvantages, and must be carefully selected according to the purpose of the experiment, the availability of raw materials and the requirements of the product, in order to achieve twice the result with half the effort.
