The present invention relates to N-(hetero)aryl-pyrrolidine derivatives of Formula I:
which are JAK inhibitors, such as selective JAK1 inhibitors, useful in the treatment of JAK-associated diseases including, for example, inflammatory and autoimmune disorders, as well as cancer.
bromination, Pd-catalyzed cyanation, and Sandmeyer diazotization/chlorination. This protocol eliminated the hazardous POCl3 of previous synthetic methods and offered a better yield (48%) which was 1.3-fold higher than a recently published procedure. From intermediate 8, the subsequent nucleophilic fluorination, nitrile hydration and hydroxyl substitution efficiently afforded the target product. Another
The present invention provides compounds useful as inhibitors of PDK1. The present invention also provides compositions thereof, and methods of treating PDK1-mediated diseases.
