| Hazard Information | Back Directory | [Description]
t-boc-N-amido-PEG2-bromide is a PEG derivative containing a bromide group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form the free amine. | [Synthesis]
The synthesis of t-boc-N-amido-PEG2-bromide is as follows:
Alcohol 64 (1 .25 g, 6.09 mmol) was dissolved in DCM (34 mL). The solution was cooled to 0°C and methanesulfonyl chloride (MsCI, 0.80 mL, 10.3 mmol, 1 .7 equiv) was added to the solution followed by Et3N (1.9 mL, 13.4 mmol, 2.2 equiv). After stirring for 3 h at rt, the reaction mixture was diluted with acetone (33 mL) and LiBr (8.9 g, 103 mmol, 17 equiv) was added. The reaction mixture was stirred overnight at rt. After that time, the solvents were evaporated under reduced pressure. The crude residue was diluted with EtOAc and washed with H20 and brine. The organic phase was dried over anhyd Na2S04. The suspension was filtered over cotton and the filtrate concentrated in vacuo. Purification by flash chromatography eluting with PE/Acetone (85:15→ 8:2) gave bromide 65 (1 .60 g, 5.95 mmol, 98%) as a colourless oil.
