실험 절차

3′-Deoxy-3′-azido-thymidine (200 mg, 0.75 mmol) was dissolved in MeOH (25 ml) and Pd/C (40 mg) was added. The suspension was stirred over a constant stream of H2 overnight. The reaction mixture was filtered, and the filtrate was concentrated. The residue was taken up in abs. EtOH (5 ml), N,N-diisopropylethylamine (0.1 ml) and 2-acetyldimedone (204 mg, 1.12 mmol) were added and the solution was refluxed for 5 h. The reaction mixture was cooled to room temperature and the product was precipitated by adding ether (50 ml) giving 3′-deoxy-3′-[1-(4,4-dimethyl-2,6-dioxocyclohex-1-ylidene)-ethylamino]-thymidine (24) (200 mg, 66%).
