A general and rapid procedure is developed for the preparation of secoribo-nucleoside analogues. Bu4NF has a marked effect on the condensation of guanine (5) with 2-(chloromethoxy)ethyl benzoate (2) or 1-halo-2-(chloromethoxy)ethanes 12 and 16. Condensation and deprotection of the acyl protecting group and nucleophilic displacement of the halogen atoms to yield 9-[(2-hydroxyethoxy)methyl] guanine (9)
