Procedure

2-Amino-9-(2-hydroxyethoxymethyl)adenine (0.25g) was dissolved in hot ethanol (50ml) and the solution cooled in an ice bath. To the cool solution was added sufficient HCl-saturated ethanol to give a pH of 1.0. Dry ether (50ml) was then added and the mixture thoroughly chilled. The resulting flesh-colored solid was removed by filtration and washed with cold ethanol. Recrystallization from methanol yielded 2-amino-9-(2-hydroxyethoxymethyl)adenine hydrochloride (0.21g., 74% of theoretical), m.p. 207°-211° C. Elemental analysis and NMR support this structure.
