Benzyl (5S)-2-(cis-4-hydroxycyclohexyl)-1-oxo-2,7-diazaspiro[4.5]decane-7-carboxylate prepared in Step 5 (0.266 g, 0.000688 mol) was dissolved in methanol (5.0 mL) and stirred under an atmosphere of hydrogen in the presence of 10% palladium on carbon (Aldrich, cat #: 520888) (20.0 mg) at r.t. for 2 h. The reaction mixture was filtered and the volatile solvents were removed under reduced pressure to afford the desired product in quantitative yield. LC/MS m/e 253.2 (M+H)+.
