실험 절차

Following the procedure of Example 1, 2,6-dichloropurine was condensed with 1-benzoyloxy-2-chloromethoxyethane to give a 41% yield of 2,6-dichloro-9-(2-benzoyloxyethoxymethyl)purine, m.p. 121°-125° C. This was treated according to the procedure of Example 2 to give simultaneous ammonolysis of the 6-chloro and benzoyloxy groups yielding 2-chloro-9-(hydroxyethoxymethyl)adenine, in 94% yield, m.p. 188°-190° C. after recrystallization from isopropanol.
