((2R,3R,4R,5R)-3-(Benzoyloxy)-4-fluoro-5-(4-methoxy-2-oxopyrimidin-1(2H)-yl)-4-methyltetrahydrofuran-2-yl)methyl Benzoate

((2R,3R,4R,5R)-3-(Benzoyloxy)-4-fluoro-5-(4-methoxy-2-oxopyrimidin-1(2H)-yl)-4-methyltetrahydrofuran-2-yl)methyl Benzoate is an intermediate in synthesizing PSI 6130 (P839680), which is an experimental treatment for hepatitis C. PSI 6130 is a member of a class of antiviral drugs known as nucleoside polymerase inhibitors. PSI 6130 inhibits the hepatitis C virus RNA dependant RNA polymerase called NS5B.
