The synthesis of methyl 4-hydroxy-1-methyl-7-phenoxy-3-isoquinoline carboxylate has been studied by chemists throughout the ages.
One method is to use a specific isoquinoline derivative as the starting material. The derivative is first taken in a suitable organic solvent, such as dichloromethane or N, N-dimethylformamide, and an appropriate amount of base, such as potassium carbonate or sodium carbonate, is added to create an alkaline environment. Subsequently, a halogen containing phenoxy groups, such as bromophenoxy compounds, is slowly added. This reaction requires temperature control, between about 50 and 80 degrees Celsius, and lasts for several hours. The phenoxy group of the halogen is nucleophilic substitution reaction, which is connected to the isoquinoline parent body to obtain 7-phenoxy isoquinoline intermediate.
Next, the intermediate is moved to a new reaction system and dissolved in an alcohol solvent, such as methanol or ethanol. Add a suitable oxidizing agent, such as potassium permanganate or potassium dichromate, and heat it moderately, about 60 to 90 degrees Celsius, so that the specific position is oxidized, and the carboxyl group is introduced, so that 4-hydroxy-1-methyl-7-phenoxy-3-isoquinoline carboxylic acid is obtained.
Finally, methanol and a catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid, are added to the above product, and under reflux conditions, an esterification reaction is carried out. When counted, 4-hydroxy-1-methyl-7-phenoxy-3-isoquinoline carboxylic acid methyl ester can be obtained.
There is another way, starting from another class of isoquinoline precursors. It is modified first, methyl is introduced, and under suitable reaction conditions, isoquinoline is methylated at a specific position with a methylating agent, such as iodomethane or dimethyl sulfate, under alkali catalysis. Thereafter, phenoxy and carboxyl groups are introduced in sequence as before, and finally esterified to obtain the target product.
All kinds of synthesis methods have their own advantages and disadvantages. Chemists should consider various factors such as the ease of obtaining raw materials, the simplicity of steps, and the high and low yield according to actual needs, and choose the best.
