실험 절차

A 3.75 g quantity of potassium hydroxide was dissolved in a mixture of 150 ml of water and 40 ml of dioxane. To the solution were added 1.00 g of 2'-deoxy-5-fluorouridine and 10 ml of 2-chlorobenzyl chloride, and the resulting mixture was stirred at 30° C. for 3 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 0.34 g of the title compound in a yield of 23%.
