Reaction Steps

Under a nitrogen atmosphere, palladium on carbon (10%, 200 mg) was added to a solution of 3-(((benzyloxy)carbonyl)amino)-N-(2-(2-(2-methoxyethoxy)ethoxy)ethyl)-N,N,3-trimethylbutan-1-aminium 4-methylbenzenesulfonate (0.93 g, 2.2 mmol) in 15 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 a clear oil (700 mg, 2.5 mmol). 1H NMR (D2O, 400 MHz) δ 1.08 (s, 6H), 1.79-1.83 (m, 2H), 2.29 (s, 3H), 3.04 (s, 6H), 3.27 (s, 3H), 3.36-3.41 (m, 2H), 3.45-3.51 (m, 4H), 3.56-3.60 (m, 6H), 3.84 (br m, 2H), 7.26-7.28 (d, J=8.0 Hz, 2H), 7.57-7.60 (d, J=8.0 Hz, 2H).
