palladium-catalyzed C–Ncross-coupling methodology, high-throughput experimentation was used to identify a catalyst capable of fusing piperidine-based nucleophiles with five-membered (hetero)aromatic bromides. A decomposition pathway for the standard electrophile was found, and a base screen was used to identify conditions that suppress this undesired transformation. Building on this, systematic optimization using
