The synthesis methods of 2-methyl-8-aminoquinoline are ancient and diverse. One method is to start with quinoline and obtain 2-methylquinoline through methylation. This process requires appropriate reaction conditions, such as the reaction with a specific reagent at a suitable temperature and pressure, so that the methyl group can be successfully connected to the second position of quinoline.
Then, 2-methylquinoline is nitrified to introduce the nitro group into the appropriate position, mostly near the 8th position. This nitrification reaction requires fine regulation of the reaction conditions, because the introduction position and quantity of nitro groups are related to the purity and yield of the final product. After nitrification, a reduction technique is performed to convert the nitro group into an amino group, resulting in 2-methyl-8-aminoquinoline. The commonly used method for this reduction step is to react with a suitable reducing agent in a specific solvent system.
There is another method, starting with a suitable nitrogen-containing heterocyclic compound and a methylating agent, first construct the basic skeleton of the quinoline, and then modify it to introduce amino groups at 8 positions and methyl groups at 2 positions. In this path, the step of constructing the quinoline skeleton is quite critical. The reaction route needs to be cleverly designed, and the appropriate reaction reagents and conditions need to be selected to ensure the correct formation of the skeleton and the smooth progress of subsequent modifications. < Br >
