実験手順

To a suspension of 2′-deoxyinosine (100 mg, 0.4 mmol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (BOP, 210 mg, 0.48 mmol) in anhydrous DMF (1 mL), N,N-diisopropylethylamine (100 μL, 0.6 mmol) was added followed by the addition of a solution of 1-(2-nitrophenyl)ethylamine (250 mg, 1.51 mmol) in DMF (1 mL). The reaction was stirred at room temperature for 64 hours. Silica gel 60 (1 g, 60-200 mesh) was added, and the mixture was evaporated in vacuo to dryness. The residue was purified by silica gel column chromatography to yield N6-[1-(2-nitrophenyl)ethyl]-2′-deoxyadenosine dA.19 (67 mg, 42%, 1:1 mixture of diastereomers) as a white foam.
