A solution of 330 mg of 2,5-anhydro-1-deoxy-1-(diethoxyphosphinyl)-1-fluoro-3,4-bis-O-(phenylmethyl)-D-glucitol D-glucitol and D-mannitol, diphenyl phosphate mixture in 20 ml of methanol was hydrogenated over palladium hydroxide catalyst until hydrogen uptake ceased. Filtration and removal of the solvent gave a yellow oil. This oil was purified by flash chromatography taking 20 ml fractions Fractions 1-26 were eluted with 3% methanol in dichloromethane and after evaporation gave 135 mg of 2,5-anhydro-1-deoxy-1-(diethoxyphosphinyl)-1-fluoro-D-mannitol, 6-(diphenyl phosphate).
