Diethyl Ether → HCID 59707722, compound

Participants

Reaction Steps

5 g 2-(Dimethylamino)ethyl methacrylate and 8.68 g tert-butyl bromoacetate were reacted in 20 ml acetonitrile for 24 h at 50° C. under N2 protection. Upon addition of 250 ml ethyl ether to the reaction mixture, the formed white crystals were isolated and dried. The resulting CB-tBu monomers were immediately stored in a desiccator at −20° C. (yield 96%). 1H NMR (D2O) δ (ppm): 1.44 (s, 9H, —OC(CH3)3), 1.87 (s, 3H, CH2═C(CH3)COO—), 3.31 (s, 6H, —CH2N(CH3)2CH2COO—), 3.98 (t, J=3 Hz, 2H, CH2═C(CH3)COOCH2CH2N(CH3)2CH2—), 4.28 (s, 2H, —CH2N(CH3)2CH2COO—), 4.60 (t, J=3 Hz, 2H, CH2═C(CH3)COOCH2CH2N(CH3)2CH2—), 5.73 and 6.10 (s, 2H, CH2═C(CH3)COO—).
