Reaction Steps

N,N′-Bis(2-tert-butoxycarbonylamino-ethyl)-2-(2-benzyloxy-ethyl)-1,3-di(tert-butoxycarbonylamino)propane (3.16 g) was dissolved in absolute ethanol (100 mL) and Pd on activated carbon (1.00 g, dry, 10%) was added. The mixture was hydrogenated in a Parr hydrogenation apparatus at 35 psi for two days. The catalyst was filtered off, washed with ethanol (3×20 mL). The ethanol was removed by rotary evaporation to give a colourless oil that was dried to a constant mass (2.67 g, 97.1%) under high vacuum.
