New discoveries in chemical research and development in 2021. In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Electric Literature of 22990-19-8, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 22990-19-8, name is 1-Phenyl-1,2,3,4-tetrahydroisoquinoline. In an article，Which mentioned a new discovery about 22990-19-8
The invention relates to a medicine intermediate, in particular to a (S)- 1 – phenyl – 1, 2, 3, 4 – tetrahydroisoquinoline preparation method; the benzoyl chloride or benzoic acid, phenethylamine, alkali metal hydroxide is mixed with water to the reaction, a proportion of N – (2 – phenylethyl) benzamide, phosphorus pentoxide, phosphorus chloride mixed with organic solvent is heating, the obtained 1 – phenyl – 3, 4 – ISO-quinoline with the 1st alcohol solvent, borohydride mixed reaction, the obtained 1 – phenyl – 1, 2, 3, 4 – ISO-quinoline with the 2nd alcohol solvent, water, D – tartaric acid mixing, heating the reaction, the obtained (S)- 1 – phenyl – 1, 2, 3, 4 – tetrahydroisoquinoline tartrate with an alkali metal hydroxide, water mixing, to obtain the target product; the invention provides (S)- 1 – phenyl – 1, 2, 3, 4 – tetrahydroisoquinoline preparation method has the preparation method, operation and the advantages of the simple post-treatment.
