A continuous flow process delivering key building blocks for a series of BCP modulator libraries is reported. A dynamically mixed flow reactor emerged as a pivotal technology in both synthesis and isolation phases enabling the processing of slurries and suspensions while maintaining high productivity and reliability. Accordingly, the synthesis of common intermediates in flow were employed to further build a pyridazone-based library (36 compounds) aimed at improving lead compound potency and selectivity while further enabling structure-activity relationship studies of a new BCP modulator family.
