[1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID is an organic compound that is widely used in various industrial applications.
The production process of this compound involves several stages, from the synthesis of its starting materials to the final product.
In this article, we will take a closer look at the production process of [1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID.

1. Synthesis of starting materials:
   The production process of [1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID begins with the synthesis of its starting materials, which are 3-amino-1,2,4-triazole-5-phenol and 1,2-diamino-4,5-methylenedioxybenzene.
   The synthesis of these starting materials involves several steps, including their respective chemical reactions and purification.
   
2. Substitution reaction:
   Once the starting materials are synthesized, they undergo a substitution reaction, which involves replacing the hydrogen atom in the amino group of the phenol with a specific functional group.
   This reaction is carried out in the presence of a strong acid catalyst and results in the formation of the corresponding amide.
   
3. Deacylation:
   The next step in the production process is the deacylation of the amide.
   This involves the removal of the carboxyl group through a hydrolysis reaction using a strong base, such as sodium hydroxide.
   The resulting product is an amine.
   
4. Hydroxylation:
   In the next step, the amine is subjected to hydroxylation, which involves the addition of a molecule of water to the nitrogen atom.
   This reaction is carried out in the presence of a hydroxylating agent, such as osmic acid, and results in the formation of the corresponding hydroxylamine.
   
5. Nitration:
   The hydroxylamine is then treated with nitric acid to introduce a nitro group.
   This reaction is carried out in the presence of a solvent, such as ethyl acetate, and results in the formation of the corresponding nitro compound.
   
6. Reduction:
   The nitro compound is then reduced to form the corresponding amino compound.
   This reaction is carried out in the presence of a reducing agent, such as lithium aluminum hydride, and results in the formation of the final product, [1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID.
   
7. Purification and isolation:
   Finally, the [1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID is purified and isolated from the reaction mixture.
   This is typically done by precipitation, crystallization, or chromatography.
   

Conclusion:
The production process of [1,2,4]TRIAZOLO[1,5-A]PYRIMIDINE-2-CARBOXYLIC ACID involves several stages, including the synthesis of its starting materials, the substitution reaction, deacylation, hydroxylation, nitration, reduction, and purification.
