3-benzyl-1,5-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-ol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 3,7-dibenzyl-1,5-dimethyl-9-hydroxy-3,7-diazabicyclo-[3.3.1]nonane (from step (i) above; 2.71 g, 7.74 mmol) in aqueous ethanol (20 mL; 95%) was 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 filtrate concentrated to give the sub-title compound in a quantitative yield.
