The Production Process of 2-Chloro-4,6-Dimethoxypyrimidine

The production of CX-543 involves several steps, which can be divided into two main stages: the synthesis stage and the purification stage.

Synthesis Stage

The synthesis stage involves the production of CX-543 through a series of chemical reactions.
The starting materials for the synthesis of CX-543 are 2,6-lutidine and chloroform.
The reaction is carried out in the presence of a strong solvent, such as ethyl acetate, and a base, such as sodium hydroxide.

The reaction between 2,6-lutidine and chloroform produces a compound known as N-chloro-2,6-dimethoxy-4-phenyl-pyrimidine.
This compound is then treated with potassium permanganate to produce N-chloro-2,6-dimethoxy-5-phenyl-pyrimidine.
Finally, the compound is treated with a reducing agent, such as hydrazine, to produce CX-543.

Purification Stage

Once the CX-543 has been synthesized, it must be purified to remove any impurities that may have been introduced during the synthesis process.
This purification stage involves several steps, including recrystallization, chromatography, and distillation.

Recrystallization involves dissolving the synthesized CX-543 in a solvent, such as ethanol or water, and then allowing the solvent to slowly evaporate.
This causes the pure CX-543 to recrystallize, while the impurities remain in Solution.

Chromatography involves passing the synthesized CX-543 through a column packed with a solid support, such as silica gel, and a mobile phase, such as a mixture of ethyl acetate and water.
The CX-543 molecules are separated from the impurities based on their size and polarity, with the pure CX-543 eluting
