5μdFUrd, 5-Fluoro-5μ-deoxyuridine - Preparation Method
Open Data Verified Data
5-fluorouracil nucleoside and p-toluenesulfonic acid monohydrate are suspended in acetone and 2,2-= methoxypropane, stirred at room temperature until clear, and excess sodium bicarbonate solid is added, stirring was continued to neutrality. Filtration, washing of the filter cake with acetone, evaporation of the wash and filtrate to dryness, and recrystallization of the resulting material from ethyl acetate gave the ketalate of 5-fluorouracil nucleoside. This was dissolved in dimethylformamide, triphenylphosphonium methyl iodide compound was added, left at room temperature, methanol was added, and the solvent was distilled off. The remaining oil was shaken with ethyl acetate and an aqueous solution of sodium thiosulfate and allowed to stand to separate. The separated ethyl acetate layer was washed with water, dried over anhydrous sodium sulfate and evaporated to dryness. The obtained oil was recrystallized from ethyl acetate to obtain a fluorourinary derivative. The obtained fluorourinary derivative was dissolved in methanol and triethylamine, and was reduced by hydrogenation under the action of a palladium-carbon catalyst at normal pressure, room temperature and vigorous stirring. The catalyst was removed by filtration and washed with methanol. The washing liquid and filter residue were evaporated to dryness, and then stirred with ethyl acetate. The treated material was reacted with aqueous trifluoroacetic acid, the reaction solution was evaporated to dryness, and ethanol was added, water and trifluoroacetic acid were removed azeotropically and evaporated to dryness. The resulting material was recrystallized from ethyl acetate to obtain doxifluridine.
