実験手順
Under a nitrogen atmosphere, 10% palladium on carbon (200 mg) was added to a solution of 3-(((benzyloxy)carbonyl)amino)-N-(2-(hexyloxy)ethyl)-N,N,3-trimethylbutan-1-aminium 4-methylbenzenesulfonate (0.95 g, 1.7 mmol) in 7 mL of methanol. The flask was degassed and placed under a hydrogen atmosphere, stirring for 18 hours at room temperature. The suspension was filtered through a pad of celite, washing with methanol, and the filtrate was concentrated under reduced pressure to give 725 mg of clear viscous oil (quantitative yield). 1H NMR (400 MHz, D2O) δ 0.75-78 (t, J=6.4 Hz, 3H), 1.09 (s, 6H), 1.7-1.26 (m, 6H), 1.47-1.51 (m, 2H), 1.80-1.84 (m, 2H), 2.30 (s, 3H), 3.03 (s, 6H), 3.36-3.40 (m, 2H), 3.44-3.48 (m, 4H), 3.81 (br s, 2H), 7.27-7.28 (d, J=8.1 Hz, 2H), 7.58-7.60 (d, J=8.1 Hz, 2H). LRMS (ESI/APCI) m/z 259 [M]+.
