The reaction of 4-(chloromethyl)-1,3-dioxolane (I) with Ac2O, HOAc and ZnCl2 gives the diacetoxy compound (II), which is treated with KOAc to yield the triacetoxy compound (III). The condensation of (III) with diacetyl guanine (IV) by means of ethylsulfonic acid affords the triacetyl ganciclovir (V), which is finally deacetylated with methylamine in methanol.
