実験手順

To a flask containing 6.0 g (11.1 mmol) [(2R,3R,4R,5R)-3,4-diacetyloxy-5-(6-chloro-2-iodopurin-9-yl)oxolan-2-yl]methyl acetate (6.4) was added 100 ml of liquid NH3 at −78° C. and the solution was allowed to stir for 6 hours. After which time it was allowed to come to r.t. overnight with concurrent evaporation of the NH3 to yield a brown oil. The product was crystallized from hot isopropanol to give 6.5 (80%), m.p. 143-145° C., r.f.=0.6 in 20% MeOH/CHCl3. 1H NMR (300 MHz, DMSO-d6) δ8.24 (s, 1H), 7.68 (s, 2H), 5.75 (d, J=6.16, 1H), 5.42 (d, J=5.40 Hz, 1H), 5.16 (d, J=4.62 Hz, 1H), 499 (t, J=5.39 Hz, 1H), 4.67 (d, J=4.81 Hz, 1H), 4.06 (d, J=3.37 Hz, 1H), 3.89 (m, 1H), 3.54 (m, 2H).
