The most common synthetic routes of 2-methyl-3-quinolinamine include the following:

1. The Hydrolysis of Chloramine-B

One of the most common methods of synthesizing 2-methyl-3-quinolinamine is through the hydrolysis of chloramine-B.
This process involves the reaction of chloramine-B with sodium hydroxide in the presence of water.
The reaction results in the formation of 2-methyl-3-quinolinamine, which can then be further processed or purified as needed.

2. The Reduction of N-Methylanthranilate

Another common method of synthesizing 2-methyl-3-quinolinamine involves the reduction of N-methylanthranilate.
This process involves the use of a reducing agent, such as hydrogen in the presence of a catalyst, to convert N-methylanthranilate into 2-methyl-3-quinolinamine.
The resulting compound can then be purified and further processed as needed.

3. The Reduction of N-Methyl-N-nitrosourea

N-methyl-N-nitrosourea is another precursor used in the synthesis of 2-methyl-3-quinolinamine.
This compound is reacted with a reducing agent, such as hydrogen in the presence of a catalyst, to form 2-methyl-3-quinolinamine.
The resulting compound can then be purified and further processed as needed.

4. The Hydrogenation of N-Methyl-N'-nitroso-N-methylurea

N-methyl-N'-nitroso-N-methylurea is another precursor used in the synthesis of 2-methyl-3-quinolinamine.
This compound is reacted with hydrogen in the presence of a catalyst to form 2-methyl-3-quinolinamine.
The resulting compound can then be purified and further processed as needed.

Overall, the synthesis of 2-methyl-3-quinolinamine is a complex process that requires careful control and purification steps to ensure the production of a pure and high-quality product.
The various synthetic routes outlined above may be used depending on the specific requirements of the application and the available resources.
