ABSTRACT:
4-Amino-1-((2R,3S,4S,5R)-5-azido-3,4-dihydroxy-5-hydroxymethyl-tetrahydro-furan-2-yl)-1H-pyrimidin-2-one (I:R1=R2=R3=R4=H) and prodrugs thereof are hepatitis C(HCV) polymerase inhibitors. Also disclosed are compositions and methods for inhibiting HCV and treating HCV-mediated diseases, processes for making the compounds and synthetic intermediates employed in the process.
