  Initial Process Development and Scale-Up of the Synthesis of a Triple Reuptake Inhibitor ALB 109780

  摘要：

  Early process development toward a triple reuptake inhibitor is described. Three different routes were evaluated; one of them was optimized and scaled up to generate 470 g of API as this route minimized the formation of undesired side products. The selected route featured Eaton's reagent-mediated cyclization of a phenyl acetamide, copper-mediated Buchwald Hartwig coupling to install a morpholine moiety, and palladium-catalyzed alpha-arylation of a dihydroisoquinolinone to construct the core structure.

  Renewed interest in covalent inhibitors of enzymes implicated in disease states has afforded several agents targeted at protein kinases of relevance to cancers. We now report the design, synthesis and biological evaluation of 6-ethynylpurines that act as covalent inhibitors of Nek2 by capturing a cysteine residue (Cys22) close to the catalytic domain of this protein kinase.

  Tetra hydroisoquinoline is a ubiquitous structural framework presented in numerous pharmacologically relevant molecules. Although accessible by the Pictet-Spengler cyclization, conditions commonly used for such cyclizations are often difficult to implement on scale. Herein, we report the development of a scaleable approach utilizing Eaton's reagent for the cyclization of substituted phenylacetamide analogues to tetrahydroisoquinoline-2-one. The development, optimization, and safety hazard evaluations, which outline the benefits and ease of workup of this new process, are discussed.
