-
Paragraph 0057-0062, (2021/03/18)
The invention relates to a synthesis method of 5, 7-dichloro-1, 2, 3, 4-tetrahydroisoquinoline hydrochloride, and belongs to the technical field of synthesis of medical intermediates. The method comprises the steps that 3, 5-dichlorobenzaldehyde serves as a raw material, 5, 7-dichloro-1, 2, 3, 4-tetrahydroisoquinoline hydrochloride is obtained through Schiff base preparation, reduction, ring closing and reductive acidification reaction, and the total yield is 60% or above. The method avoids using expensive raw materials, and is simple in process route, mild in condition, low in production costand suitable for industrial production.

The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (MIC 10.2 μg/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 μg/mL), and N-butyl-3,5-difluorobenzylamine (MIC 6.4 μg/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combination of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.
