Versuchsvorschrift

To a solution of 6-chloropurine (6 g, 38.8 mmoles) in DMF was added sodium hydride 60% (0.93 g) over 1.5 hour period. (2-acetoxyethoxy)methyl bromide was then added at room temperature; the reaction mixture was allowed to stir for 2 hours under Nz atmosphere. H2O was added and the product was extracted with ethyl acetate. The organic phase was dried over MgSO4, filtered, and evaporated in vacuo to give a light yellow solid 7.1 g, 68% yield of 9-[(2-acetoxy-ethoxy)methyl]-6-chloro-purine. The crude was used without further purification.
