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. (C) 2003 Elsevier Ltd. All rights reserved.
