Kozai, Shigetada,Maruyama, Tokumi
, p. 574 - 575 (1999)
Mitsunobu reaction of 2,6-dichloropurine with 2,6-difluorobenzyl alcohol gave 2,6-dichloro-9-(2,6-difluorobenzyl)-9H-purine and 7-benzylated congener in 73% and 10% yield, respectively. Treatment of the former compound with ammonia gave 2-chloro-9-(2,6-di
