Hypoxanthine is treated as in the procedure of Example 1 with glycidol in the presence of potassium carbonate to give 1-(hypoxanthine-9-yl)-2,3-propandiol. The resulting 1-(9-hypoxanthine)-2,3-propandiol is treated with dimethoxytrityl chloride in pyridine as in Example 2 to give 1-(9-hypoxan-thine)-3-O-dimethoxytrityl-2-propanol. The resulting 1-(9-hypoxanthine)-3-O-dimethoxytrityl-2-propanol is phosphitylated with chloro-β-cyanoethoxy-N,N-diisopropylaminophosphine as per Example 3 to give the title compound.
