3,8-Dibenzyl-3,8-diazabicyclo[3.2.1]octan-2,4-dione hydrochloride (39 g, 0.11 mol; from step (c) above) was added to a suspension of 10% Pd/C (500 mg) in methanol (500 mL) under a blanket of N2. The N2 atmosphere was exchanged for H2 (one atmosphere of pressure). The reaction was stirred vigorously overnight. The catalyst was removed by filtration and the filtrate concentrated in vacuo to afford 28.3 g (96%) of the sub-title compound as a light tan solid.
