Development of an Efficient Pd-Catalyzed Coupling Process for Axitinib
摘要:
The manufacturing process of axitinib (1) involves two Pd-catalyzed coupling reactions, a Migita coupling and a Heck reaction. Optimization of both of these pivotal bond-formation steps is discussed as well as the approach to control impurities in axitinib. Essential to the control strategy was the optimization of the Heck reaction to minimize formation of impurities, in addition to the development of an efficient isolation of crude axitinib to purge impurities.

A new approach to C−Scouplings is reported that relies on nickel catalysis undermildconditions, enabled by micellar catalysis in recyclable water as the reaction medium. The protocol tolerates a wide range of heteroaromatic halides and thiols, including alkyl and heteroaryl thiols, leading to a variety of thioethers in good isolated yields. The method is scalable, results in low residual metal in
