The present disclosure provides processes for the preparation of a compound of formula I: 115-. (canceled) This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/920,446 filed on Dec. 23, 2013, the entirety of which is incorporated herein by reference.The present disclosure relates generally to the field of organic synthetic methodology for the preparation of Flaviviridae virus inhibitor compounds and their synthetic intermediates.The hepatitis C virus (HCV), a member of the hepacivirus genera within the Flaviviridae family, is the leading cause of chronic liver disease worldwide (Boyer, N. et al. J Hepatol. 2000, 32, 98-112). Consequently, a significant focus of current antiviral research is directed toward the development of improved methods for the treatment of chronic HCV infections in humans (Ciesek, S., von Hahn T., and Manns, M P., Clin. Liver Dis., 2011, 15, 597-609; Soriano, V. et al, J. Antimicrob. Chemother., 2011, 66, 1573-1686; Brody, H., Nature Outlook, 2011, 474, S1-S7; Gordon, C. P., et al., J. Med. Chem. 2005, 48, 1-20; Maradpour, D., et al., Nat. Rev. Micro. 2007, 5, 453-463).Virologic cures of patients with chronic HCV infection are difficult to achieve because of the prodigious amount of daily virus production in chronically infected patients and the high spontaneous mutability of HCV (Neumann, et al., Science 1998, 282, 103-7; Fukimoto, et al., Hepatology, 1996, 24, 1351-4; Domingo, et al., Gene 1985, 40, 1-8; Martell, et al., J. Virol. 1992, 66, 3225-9). HCV treatment is further complicated by the fact that HCV is genetically diverse and expressed as several different genotypes and numerous subtypes. For example, HCV is currently classified into six major genotypes (designated 1-6), many subtypes (designated a, b, c, and so on), and about 100 different strains (numbered 1, 2, 3, and so on).HCV is distributed worldwide with genotypes 1, 2, and 3 predominate within the United States, Europe, Australia ...
