| Description | t-Boc-N-Amido-PEG1-amine is a small molecule PEG reagent containing an amino group and Boc-protected amino group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc group can be deprotected under mild acidic conditions to form the free amine. | | Chemical Properties | Colorless viscous liquid | | Uses | Amino-PEG2-NH-Boc is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. | | Synthesis | Step 4: Synthesis of tert-butyl [2-(2-aminoethoxy)ethyl]carbamate (58)
Under argon protection, tert-butyl (2-(2-azidoethoxy)ethyl)carbamate (57, 5.0 g, 0.0217 mol) was dissolved in methanol (100 mL) and palladium/carbon catalyst (2.5 g, 10 mL) was added. The reaction mixture was stirred overnight at room temperature under hydrogen (50 psi) atmosphere. Upon completion of the reaction, the catalyst was removed by filtration through a diatomaceous earth pad and the filtrate was concentrated under reduced pressure to afford tert-butyl [2-(2-aminoethoxy)ethyl]carbamate (58, 3.0 g). The resulting product can be used directly in the subsequent reaction without further purification.
