Abstract
In this study, we described developing a refined manufacturing process for S-892216, a second-generation COVID-19 therapeutic agent currently under development. The focus of this research was on the feasibility of commercial manufacturing. In particular, we developed a manufacturing process that facilitates the stable acquisition of a specific crystal form for intermediate or maximum reaction efficiency using flow chemistry, eliminating the need for excessive extraction, concentration, and purification operations. Compared to the first-generation process used during early phase clinical trials, the overall yields (increasing from 41% to 62%) and PMI values (decreasing from 323 to 210) improved significantly. These advancements underscore the potential of the second-generation process for S-892216 to strengthen the supply chain of COVID-19 therapeutics.
期刊介绍:
The journal Organic Process Research & Development serves as a communication tool between industrial chemists and chemists working in universities and research institutes. As such, it reports original work from the broad field of industrial process chemistry but also presents academic results that are relevant, or potentially relevant, to industrial applications. Process chemistry is the science that enables the safe, environmentally benign and ultimately economical manufacturing of organic compounds that are required in larger amounts to help address the needs of society. Consequently, the Journal encompasses every aspect of organic chemistry, including all aspects of catalysis, synthetic methodology development and synthetic strategy exploration, but also includes aspects from analytical and solid-state chemistry and chemical engineering, such as work-up tools,process safety, or flow-chemistry. The goal of development and optimization of chemical reactions and processes is their transfer to a larger scale; original work describing such studies and the actual implementation on scale is highly relevant to the journal. However, studies on new developments from either industry, research institutes or academia that have not yet been demonstrated on scale, but where an industrial utility can be expected and where the study has addressed important prerequisites for a scale-up and has given confidence into the reliability and practicality of the chemistry, also serve the mission of OPR&D as a communication tool between the different contributors to the field.
