Procedure

To a solution of di-tert-butyl 2-[((tert-butoxy)-{[benzylamino]methyl}phosphoryl)methyl]pentane-1,5-dioate (8.20 g, 16.5 mmol) in ethanol (100 mL) was added palladium on carbon (0.50 g), and the suspension was shaken under hydrogen (50 psi) for 4 days. The catalyst was removed by filtration through a pad of Celite. The filtrate was concentrated to give 6.629 g of colorless oil (99% yield).
