10. A method of making a soluble prodrug of a tertiary amine containing parent drug comprising derivatization of a prodrug moiety of formula VII ##STR30## wherein A represents a leaving group, R4 and R5 are each hydrogen or an organic residue selected from the group consisting of a straight-chain, substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, and a substituted or unsubstituted cyclic group, R4 and R5 may contain one or more heteroatoms and may also be joined to form a ring, and Y is a phosphate protecting group,
through the nucleophilic attack of a tertiary amine causing the displacement of A, followed by the removal of the protecting groups.
- 14. A method of making a soluble prodrug of a tertiary amine containing parent drug comprising reaction of a compound of the following Formula VIII ##STR31## wherein R4 and R5 are each an organic or inorganic residue, and W and Z are leaving groups, with a tertiary amine to displace one of either W or Z and reacting the remaining leaving group with a protected phosphate.
