The hydrogenation reaction results in the conversion of nitrobenzene to Isoquinolin-3-ylmethanamine.
This route is highly efficient, with a yield of almost 100%.

2. Williamson Ether Synthesis

The Williamson Ether Synthesis is another commonly used synthetic route for the synthesis of Isoquinolin-3-ylmethanamine.
In this process, bromoethane is treated with sodium hydroxide to form a sodium bromide, which is then reacted with potassium hydroxide and calcium oxide to form an ether.
The ether is then treated with chloroform and a base, such as sodium hydroxide, to yield Isoquinolin-3-ylmethanamine.
This route is highly efficient, with a yield of almost 90%.

3. Mannich Reaction

The Mannich reaction is another commonly used synthetic route for the synthesis of Isoquinolin-3-ylmethanamine.
In this process, formaldehyde, benzaldehyde, and a primary amine are reacted in the presence of an acid catalyst such as sulfuric acid.
The reaction results in the formation of Isoquinolin-3-ylmethanamine.
This route is highly versatile, with the choice of reactants allowing for the synthesis of a wide range of isoquinolinylmethylamines.

4. Reduction of Nitrosobenzene

The reduction of nitrosobenzene is another synthetic route for the synthesis of Isoquinolin-3-ylmethanamine.

This route is highly efficient, with a yield of almost 90%.

5. Direct Amination of Benzene

The direct amination of benzene is another method for the synthesis of Isoquinolin-3-ylmethanamine.
In this process, benzene is treated with an ammonia solution and a catalyst such as Raney nickel to yield Isoquinolin-3-ylmethanamine.
This route is highly efficient, with a yield of almost 80%.

6. Reduction of Nitrobenzene with Hydrazine

The reduction of nitrobenzene with hydrazine is a highly efficient and cost-effective method for the synthesis of Isoquinolin-3-ylmethanamine.
In this process, nitrobenzene is treated with hydrazine in the presence of a catalyst such as palladium on barium oxide.
The reaction results in the formation of Isoquinolin-3-ylmethanamine.
This route is highly efficient, with a yield of almost 90%.
