Mode opératoire

1.0 g of Boc-Lys(Cbz)-OMe (5) was dissolved in 40 mL MeOH:Ethyl acetate. 100 mg of Palladium on active carbon (Pd/C) was added to the solution. The solution was stirred under hydrogen for 2 hrs. The organic solution was filtered through Celite and washed with 10 mL MeOH. The filtrate was evaporated under reduced pressure to yield Boc-Lys-OMe of formula (6)
