In this article, we will discuss the synthetic routes of this compound and the importance of this research in the field of pharmaceuticals.

Background

4-chloro-6-(4-methylphenyl)-2-(methylthio)pyrimidine-5-carbonitrile, also known as CX-1702, is a potent and selective inhibitor of the enzyme dihydroorotate dehydrogenase (DHODH).
This enzyme plays a crucial role in the pyrimidine metabolism of cells, and its inhibition has been shown to have antiproliferative effects on various cancer cell lines.
Therefore, CX-1702 has garnered significant attention as a potential cancer treatment.

Synthetic Routes

There are several synthetic routes that have been reported for the synthesis of CX-1702.
One of the most common methods is the Stille coupling reaction, which involves the reaction of a halogenated pyrimidine with a chloromethyl vinyl ketone using palladium(II) acetate as a catalyst.
This method yields the 4-chloro-6-(4-methylphenyl)-2-(methylthio)pyrimidine-5-carbonitrilee intermediate, which can then be reduced to the final product using a reducing agent such as lithium aluminum hydride.

Another synthetic route for CX-1702 involves the reaction of 4-chloro-6-(4-methylphenyl)pyrimidine-5-carbonitrile with 2-(methylthio)pyrimidine-5-sulfonic acid in the presence of a base such as potassium carbonate.
This method yields the final product after treatment with a reducing agent, such as tributylphosphine.

The Role of Chemical Synthesis in the Development of Pharmaceuticals

The synthesis of CX-1702 serves as an example of the importance of chemical synthesis in the development of new drugs.
The ability to synthesize novel compounds is crucial for the discovery of potential treatments for various diseases.
In the case of CX-1702, the synthetic routes reported to date not only provide a means for the generation of sufficient quantities of the compound for testing, but also serve as a starting point for the optimization of the synthesis and the identification of new routes.

Furthermore, chemical synthesis plays an important role in the optimization of compounds in terms of their bioavailability, pharmacokinetics, and pharmacodynamics.
This involves the synthesis of derivatives of the initial compound that may have improved properties, as well as the synthesis of the final compound using alternative methods that may result in higher yields or more efficient synthesis.
