ABSTRACT:
The present invention provides a process for the synthesis of penciclovir and famciclovir by 9-substituting 2-amino-6-chloropurine (ACP) with an appropriate side chain precursor, followed by conversion of the 6-chloro moiety to a hydroxy moiety (i.e. to form a guanine) or hydrogen (to form a 2-aminopurine), respectively; and 2-acetoxymethyl-4-halo-butyl-1-yl acetates.
