3,7-Dibenzyl-3,7-diazabicyclo[3.3.1]nonane (1.97 g; 6.4 mmol; from step (a) above) was dissolved in EtOH (95%) and hydrogenated over 5% Pd/C at 1 atm. until tlc indicated that the reaction was complete. The catalyst was removed by filtration through a pad of celite and the residue was concentrated under reduced pressure to give the title compound in a quantitative yield.
