Development of Pilot-Scale Continuous Production of an LY2886721 Starting Material by Packed-Bed Hydrogenolysis
25 Jun 2024 | Contributor(s):: Zaborenko, Nikolay, Linder, Ryan J., Braden, Timothy M., Campbell, Bradley M., Hansen, Marvin M., Johnson, Martin D.
The design, development, and implementation of a pilot-scale continuous hydrogenolysis in a catalytic packed bed to generate a starting material is described. Control of a critical defluorination impurity under the reaction conditions has been achieved by reducing residence time inside the...
Pilot-Scale Continuous Production of LY2886721: Amide Formation and Reactive Crystallization
10 May 2024 | Contributor(s):: Polster, Christopher S., Cole, Kevin P., Burcham, Christopher L., Campbell, Bradley M., Frederick, Andrea L., Hansen, Marvin M., Harding, Molly, Heller, Michael R., Miller, Michael T., Phillips, Joseph L., Pollock, Patrick M., Zaborenko, Nikolay
The design, development, and implementation of a pilot-scale continuous Schotten–Baumann amide bond formation and reactive crystallization to afford LY2886721 is described. The material met all API quality attributes and was comparable to material produced by a defined batch process. The...
