Versuchsvorschrift

A 7.5 g quantity of potassium hydroxide was dissolved in a mixture of 300 ml of water and 80 ml of dioxane. To the solution were added 2.00 g of 2'-deoxy-5-fluorouridine and 4.9 ml of 4-fluorobenzyl chloride, and the resulting mixture was stirred at 35° C. for 2 days. After the reaction, the same subsequent procedure as in Reference Examples 4 and 5 was carried out, and the residue was placed on a silica gel column and eluted with 2% methanol-chloroform, thereby producing 0.57 g of the title compound in a yield of 20%.
