Procedure
To a stirred solution of ((2R,4R)-3-acetoxy-5-(6-chloro-9H-purin-9-yl)-4-fluoro-3,4-dimethyl-tetrahydrofuran-2-yl)methyl benzoate (about 0.3 g, 0.64 mmol) in ethanol (about 5 ml) was added morpholine (about 0.56 ml, 6.49 mmol) and stirred at room temperature for about 15 hours. Completion of the reaction mixture monitored by thin-layer chromatography, water added to the reaction mixture and the aqueous layer was extracted with ethyl acetate and the combined organic layers were washed with brine and dried over sodium sulphate. Concentration under reduced pressure and purification by silica gel column chromatography using 40% ethyl acetate in hexane as eluent furnished title compounds Isomer A and B (0.1 g) as a colorless gummy mass. Yield: 30%.
