Versuchsvorschrift
To a solution of N-Cbz-4-hydroxy-L-proline ethyl ester (3.29 g) in 40 ml ethanol was added 6 ml of ethanol saturated with gaseous HCl followed by 10% palladium on carbon (0.50 g). The mixture was hydrogenated on a Parr Hydrogenator at 30-40 psi for 3 hours. The solution was filtered over celite and concentrated in vacuo to provide 2.09 g of the crystalline product.
