DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) The present invention provides a nucleosides comprising a pyrazolopyrimidine base I and a process for producing the same. In particular, the processes of the present invention comprises using a halogenated pyrazolopyrimidine base and removing the halogen after the base is coupled to a sugar moiety. The presence of the halogen on the nucleoside base allows facile and economical prodn. of a large quantity of nucleosides. Thus, II was prepd. via halogenation reaction and using photolabile hydroxy protecting groups. ..
