Treatment of 5'-O-benzoylthymidine 1 with a mixture of acetic anhydride. acetic acid and dimethyl sulfoxide yielded 5'-O-benzoyl-3'-O-methylthiomethylthymidine 2, which was converted via the 3'-O-bromomethyl derivative into 3'-O-(omega-aminoalkoxymethyl)thymidines 7 bearing a 6, 8 or 10 methylene groups long hydrocarbon chain, and finally to their 5'-triphosphates 10. The latter compounds were shown to be terminators of DNA synthesis catalysed by thermostable Tet/z DNA-polymerase, and may be labelled at the aliphatic amino group with fluorescent probes.
