Alkylated piperazine compounds of Formula I are provided, including stereoisomers, tautomers, and pharmaceutically acceptable salts thereof, useful for inhibiting Btk kinase, and for treating immune disorders such as inflammation mediated by Btk kinase. Methods of using compounds of Formula I for in vitro, in situ, and in vivo diagnosis, and treatment of such disorders in mammalian cells, or associated pathological conditions, are disclosed.
The development of an expedient synthesis to GDC-0852 (1), a reversible BTK inhibitor drug candidate, is described. The key starting material tricyclic lactam 5 was prepared by an annulation reaction of unprotected piperidine-2-carbaldehyde HCl salt (20) and N-Boc piperidine-2,4-dione 21 in a safe and scalable manner. A highly selective Pd-catalyzed CN coupling of lactam 5 and linker 2a, followed by
