Reaction Steps

(2R,3R,4R,5R)-4-(acetyloxy)-2-(2,6-dichloro-9H-purin-9-yl)-5-(5-ethylisoxazol-3-yl)tetrahydrofuran-3-yl acetate (125 mg) was dissolved in isopropanol (5 ml) and the solution was treated with diisopropylethylamine (0.06 ml) followed by 1-ethylpropylamine (0.044 ml). The mixture was heated at 50° C. under nitrogen for 16 h. The solvent was removed in vacuo and the mixture partitioned between ethyl acetate and 1 M hydrochloric acid. The organic layers were washed with saturated sodium bicarbonate solution and brine, dried (MgSO4) and evaporated in vacuo. Purification by chromatography on silica gel (Varian Bondelut cartridge), eluting with (i) dichloromethane, (ii) ether and (iii) ethyl acetate, gave the title compound as a colourless oil (108 mg).
