ABSTRACT:
A process for the preparation of acyclovir includes contacting an at least partially silylated guanine or mixture of at least partially silylated guanines with 1,3-dioxolane in the presence of a selective alkylation catalyst selected from the group consisting of trifluoromethanesulfonic acid, trimethylsilyl trifluoromethanesulfonate, and bistrimethylsilyl sulfonate, and hydrolyzing the product thus formed.
