Procedure

A solution of sodium benzylate in benzyl alcohol was prepared from sodium (2.58 g) and benzyl alcohol (28 ml). The solution was heated to 120° C. and 2-amino-6-chloro-9-(2-benzyloxyethoxymethyl)purine (3.47 g) was added over a 10 minute period. The reaction mixture was headed overnight with stirring at 120°-130° C. and then poured into a mixture of ice and water. The resulting mixture was extracted thoroughly with chloroform. The aqueous phase was neutralized with acetic acid, giving a white precipitate which was recrystallized from methanol and then from water to give analytically pure 2-amino-6-benzyloxy-9-(2-hydroxyethoxymethyl) purine, m.p. 291°-292° C. (dec.) in 50% yield.
