Novel Bromination Process slashes PMI

CatSci was tasked with designing a new bromination method for a key reaction intermediate. Use of bromine rendered the previous process unsuitable for a larger campaign and would require expensive and time-consuming alterations to the plant.

Route Redesign to Eliminate Use of PhOCN

The route supplied by the client involved the use of phenyl cyanate for functionalising a heterocyclic intermediate with a nitrile group. Its ongoing use would require cyanide monitoring, a dedicated waste stream treatment step, and there were concerns over the sourcing of material of appropriate quality over the long term.

Development of a Late-Stage Buchwald Amination

CatSci was tasked with the development of a regioselective Buchwald-Hartwig amination for the final bond forming step of an API. The inherited conditions were not robust with respect to reaction conversion leading to stability concerns.

Solubility Data Driven Workup Design & Crystallisation Development

CatSci was tasked with designing a new bromination method for a key reaction intermediate. Use of bromine rendered the previous process unsuitable for a larger campaign and would require expensive and time-consuming alterations to the plant.
