Abstract
2-Pyridones were prepared from 2,6-dibromopyridine via a multi-step synthesis. A variety of chemical transformations, including regioselective nucleophilic addition and selective nitrogen alkylation, afforded the penultimate intermediate 9. A combination of two-dimensional NMR techniques to unequivocally assign the structure of 9 is described. Compound 9 was then used in a Suzuki coupling and further derivatized to afford the targeted tissue Factor VIIa inhibitors. These compounds were tested in several serine protease enzyme assays with biological activity reported.
