Abstract
The present invention provides novel synthesis's for obtaining a protecting group aminoxy PEG-6 linker from cost effective, and readily available starting materials and chemicals or modified polyethylene glycols. More specifically, a novel synthesis of obtaining a modified Boc-protected aminoxy PEG-6 linker was achieved so that said linker may be attached to a vector such as a peptide based fragment.
