2-(2-t-Butylaminoethoxy)ethyl acetate (1.2 g, 5.9 mmol) was stirred for 7 hours with sodium methoxide (0.015 g, 0.28 mmol) in methanol (15 mL) at room temperature. The NMR analysis of the reaction mixture showed approximately 20% conversion. Additional sodium methoxide (0.015 g, 0.28 mmol) was added to the reaction mixture and it was stirred for an additional 3 hours. Solvent was evaporated and the liquid phase was separated from the solid by filtration. The solid was washed with diethyl ether. The combined filtrates were evaporated under reduced pressure to remove a solvent to give 2-(2-t-butylamino-ethoxy)ethanol (EETB) as yellowish liquid (0.65 g, 70%) 1H NMR δ 1.12 (s, 9H), 2.76 (t, J=5.1 Hz, 2H), 3.59-3.66 (m, 4H), 3.70-3.73 (m, 2H); 13C NMR δ 28.8, 42.2, 50.3, 61.8, 71.3, 72.6.
