Benzyl 3-(4-(tert-butoxycarbonyl)phenyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carboxylate (0.62 g, 1.14 mmol) and palladium on carbon (10 wt. %, wet, Degussa type E101 NE/W,) (0.12 g) in ethyl acetate (5 mL) and methanol (5 mL) was stirred at room temperature under hydrogen (balloon) for 3 hours. The catalyst was removed by filtration and the filtrate evaporated and dried under vacuum to give product as foam (0.46 g, quant.); MS for C24H29N3O3 m/z 408 (M+H)+.
