Floxuridine → 3-Benzoyl-2'-deoxy-5-fluorouridine

関与物質

反応手順

15 Grams of 2'-deoxy-5-fluoro uridine (FudR) was dissolved in 45 ml of dimethylacetamide. Thereto was added 9 ml of triethylamine. To the mixture being cooled with ice-water was added 8.6 g of benzoyl chloride and the whole mixture was stirred overnight. The reaction mixture was subjected to filtration. The resulting filtrate was subjected to evaporation to obtain the residue, and water was added to the residue. The aqueous solution was extracted with ethyl acetate, and the organic layer was dried with anhydrous sodium sulfate. The dried ethyl acetate solution was concentrated and the residue was recrystallized from ethanol to obtain the desired compound. The yield was 10.5 g. M.p. 126° to 127° C.
