In this article, we will discuss some of the most commonly used synthetic routes for the synthesis of (4-Chloro-5-methyl-pyrimidin-2-yl)-ethyl-amine.

One of the most common methods of synthesizing (4-Chloro-5-methyl-pyrimidin-2-yl)-ethyl-amine is through the reaction of 2,4-diamino-6-methoxy-pyrimidine with chloroacetyl chloride in the presence of a strong acid catalyst, such as sulfuric acid or trifluoroacetic acid.
This reaction results in the formation of a secondary amine, which is then reduced to an alkylamine using a reducing agent, such as lithium aluminum hydride or hydrogen in the presence of a catalyst, such as palladium on barium oxide.

Another synthetic route to (4-Chloro-5-methyl-pyrimidin-2-yl)-ethyl-amine involves the reaction of 2,4-diamino-6-methoxy-pyrimidine with chloroformyl chloride in the presence of a Lewis acid catalyst, such as ferric chloride or aluminum chloride.
This reaction results in the formation of an N-chloroamide, which can then be converted to an amine using a reducing agent, such as lithium aluminum hydride or hydrogen in the presence of a catalyst, such as platinum on barium oxide.

A third synthetic route to (4-Chloro-5-methyl-pyrimidin-2-yl)-ethyl-amine involves the reaction of 2,4-diamino-6-methoxy-pyrimidine with chloroacetic acid in the presence of a strong base, such as sodium hydroxide or potassium hydroxide.
This reaction results in the formation of an N-chloroethanolamine, which can then be reduced to an alkylamine using a reducing agent, such as lithium aluminum hydride or hydrogen in the presence of a catalyst, such as palladium on barium oxide.

In addition to these synthetic routes, (4-Chloro-5-methyl-pyrimidin-2-yl)-ethyl-amine can also be synthesized through the reaction of 2,4-diamino-6-methoxy-pyrimidine with various other chlorinated compounds, such as chloroacetic acid, chloroformic acid, or chloroaldehyde.
