2. Diazotization reaction: The first step in the synthesis of (5-chloro-pyrimidin-2-yl)-ethyl-amine is the diazotization reaction.
   In this reaction, 2-chloropyrimidine is treated with a solution of nitric acid and sodium nitrite in a solvent such as water or acetonitrile.
   This results in the formation of 2-chloropyrimidine-1,4-dione, which is then treated with ethylamine in the presence of a catalyst such as aluminum chloride.
   
3. Reduction reaction: The next step in the synthesis of (5-chloro-pyrimidin-2-yl)-ethyl-amine is the reduction reaction.
   In this reaction, the 2-chloropyrimidine-1,4-dione formed in the diazotization reaction is reduced to form 2-chloropyrimidine-1-ethanol using a reducing agent such as lithium aluminum hydride (LiAlH4).
   
4. Deprotection reaction: The final step in the synthesis of (5-chloro-pyrimidin-2-yl)-ethyl-amine is the deprotection reaction.
   In this reaction, the 2-chloropyrimidine-1-ethanol formed in the reduction reaction is treated with a base such as sodium hydroxide to remove the ethanol protecting group.
   This results in the formation of the final product (5-chloro-pyrimidin-2-yl)-ethyl-amine.
