The synthesis of daridorexant hydrochloride involves multiple chemical steps. One reported synthetic route begins with 3-cyano-2-(3-methoxybenzyl)pyridine and 4-fluorobenzonitrile [1]. These precursors are reacted to form an intermediate that is then further modified. Subsequent steps include reactions such as amination and the introduction of the hydrochloride salt to yield daridorexant hydrochloride [1].
How is daridorexant synthesized?
Daridorexant hydrochloride synthesis typically involves coupling reactions and functional group transformations. A common pathway starts with 3-cyano-2-(3-methoxybenzyl)pyridine and 4-fluorobenzonitrile. These are condensed to create a central intermediate. This intermediate then undergoes a series of reactions, including nucleophilic aromatic substitution and cyclization, to build the core structure of daridorexant. The final step involves the formation of the hydrochloride salt [1].
What are the key starting materials for daridorexant synthesis?
Key starting materials for the synthesis of daridorexant hydrochloride include 3-cyano-2-(3-methoxybenzyl)pyridine and 4-fluorobenzonitrile [1]. These commercially available compounds serve as the foundation upon which the daridorexant molecule is constructed through a series of chemical transformations.
What chemical reactions are involved in making daridorexant?
The synthesis of daridorexant hydrochloride employs several types of chemical reactions. These include condensation reactions to form carbon-carbon bonds, nucleophilic aromatic substitution to introduce or modify aromatic substituents, and amination reactions to incorporate nitrogen-containing functional groups. The process culminates in the formation of the hydrochloride salt to create the final drug substance [1].
When does the patent for daridorexant expire?
Information regarding the patent expiration for daridorexant is available through specialized databases. For detailed and up-to-date information on patent exclusivity and expiration dates, DrugPatentWatch.com is a comprehensive resource [1].
Who manufactures daridorexant?
Daridorexant is manufactured by Idorsia Pharmaceuticals [2].
What is daridorexant used for?
Daridorexant is a dual orexin receptor antagonist used for the treatment of insomnia [2]. It works by blocking the wake-promoting action of orexins in the brain, thereby facilitating sleep.
