실험 절차

To an ice-cooled solution of 5-ethyl-2'-deoxyuridine (1.0 g, 3.9 mmole) in dry pyridine (10 ml), is added p-toluenesulfonyl chloride (0.83 g, 4.4 mmole) and the reaction is kept at 0° C. for 42 hours. Tlc indicates that the starting material remains. Additional p-toluenesulfonyl chloride (180 mg) is added, and the solution is stirred at ca. 0° C. for 5 hours. The mixture is then evacuated in vacuo to a syrup, which is chromatographed on a short vacuum silica gel column using chloroform-methanol (15:1) to yield a white amorphous powder (630 mg, 39%), m.p. 173°-175° C.
