Versuchsvorschrift

The hydroxyl group of the sugar part of alkynylamino nucleoside 69 (0.167 mmol) was converted to a triphosphate and the trifluoroacetyl group was removed following the general procedure given in Example 1E. After addition of the second aliquot of phosphorus oxychloride, phosphorylation was allowed to proceed for for 75 min. Assuming an absorption coefficient for the product equal to that of the starting material (7,790), the yield of triphosphate 67, based on its UV absorption at 291 nm, was 21%.
