A scalablesynthesis of a pan-JAK inhibitor is described. The original synthesis by the Medicinal Chemistry group has been modified to develop a new protecting group strategy, a 3-step telescoped synthesis to generate an imidazole ring from a nitrile, and a telescoped borylation/Suzuki coupling sequence as well as to replace HATU with process-friendly CDI in the final amidation step.
