2022 Peter J. Dunn Award for Green Chemistry & Engineering Impact in the Pharmaceutical Industry
A team from Merck in Rahway, NJ is the recipient of the 2022 Peter J. Dunn Award for Green Chemistry and Engineering Impact in the Pharmaceutical Industry. Merck team members receiving the award are Karla Camacho Soto, Mike DiMaso, Jacob Forstater, Nadine Kuhl, Reed Larson, Chris Prier, and Ben Turnbull.
The initial manufacturing process for nemtabrutinib—acquired through the purchase of ArQule, Inc.—relied on an 11-step synthesis. The Merck team was able to reduce this to two steps. They were also able to replace toxic solvents with biorenewable Cyrene, avoid a highly energy-intensive transformation, and employ catalysis to improve efficiency. Three new technologies were employed to contribute to the sustainability of the process: biocatalysis, enzyme immobilization, and continuous manufacturing in a packed-bed reactor. Merck estimates that the new process reduces energy utilization 70%, as well as seeing a 70% reduction in both carbon dioxide and wastewater generation.
“The development and deployment of enabling technologies that support the most robust long-term supply of our medicines and vaccines is a primary goal of our process research and development team, and we are confident that biocatalysis will continue to grow as a key driver of efficient manufacturing processes,” says L.-C. Campeau, Associate Vice President and the Head of Small Molecule Process Research & Development at Merck.
