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. Examination of the crystal

explore diverse sets of reaction conditions, and problems with product purification. In contrast, product isolation from TFA‐TFE reactions is straightforward: evaporation of the reaction mixture, basification and chromatography affords analytically pure material. A total of 45 examples are described with seven discrete heterocyclic scaffolds and 2‐, 3‐ and 4‐substitutedanilines giving product yields
