   25 Jun 2024 | Contributor(s):: Qin, Yangzhong, Mattern, Keith A., Zhang, Victoria, Abe, Kotoe, Kim, Jungchul, Zheng, Michelle, Gangam, Rekha, Kalinin, Alexei, Kolev, Joshua N., Axnanda, Stephanus, Dance, Zachary E. X., Ayesa, Umme, Ji, Yining, Grosser, Shane T., Appiah-Amponsah, Emmanuel, McMullen, Jonathan P.

   Belzutifan has been approved recently by the U.S. Food and Drug Administration (FDA) for treating patients with certain types of Von Hippel-Lindau (VHL) disease-associated tumors. Although a commercial synthetic process has been established to make belzutifan, a further optimized process with...

   A scalable and efficient synthesis of hydroxyindanone 3, a key intermediate for belzutifan (MK-6482), is described. Mechanistic studies revealed the sensitivity of the reduction reaction toward the CO2 byproduct. Special effort was required to design a scale-insensitive process for the removal of...

3. Manufacturing Process Development for Belzutifan, Part 2: A Continuous Flow Visible-Light-Induced Benzylic Bromination

   25 Jun 2024 | Contributor(s):: Bottecchia, Cecilia, Lévesque, François, McMullen, Jonathan P., Ji, Yining, Reibarkh, Mikhail, Peng, Feng, Tan, Lushi, Spencer, Glenn, Nappi, Jarod, Lehnherr, Dan, Narsimhan, Karthik, Wismer, Michael K., Chen, Like, Lin, Yipeng, Dalby, Stephen M.

   We report the development and scale-up of a continuous flow photochemical benzylic bromination en route to belzutifan (MK-6482), a small molecule for the treatment of renal cell carcinoma associated with Von Hippel–Lindau syndrome. Compared with the clinical supply route, the photochemical...
