반응 단계

2.1 g of p(EG1k-Asp) (1.77 mmol —NH2) was dissolved in 30 mL of DCM and 15 mL of DMF. 842 mg of N-Boc-DOPA (2.83 mmol), 382 mg of HOBt (2.83 mmol), HBTU (2.83 mmol), and 595 μL of Et3N (4.25 mmol) were added. The mixture was stirred for 1 hr at room temperature and added to 450 mL ethyl ether. The polymer was further precipitated in cold MeOH and dried in vacuum to yield 1.9 g of PEE-1 (GPC: Mw=33,800, PD=1.3; UV-vis: 7.7±1.3 wt % DOPA).
