Versuchsvorschrift
0.224 g of N2 -(benzyloxycarbonyl)-N1 -tert.butyl-4(R)-hydroxy-L-prolinamide was dissolved in 20 ml of ethanol and hydrogenated over 50 mg of 10% palladium-on-carbon at room temperature and under atmospheric pressure for 2 hours. The catalyst was filtered off and the filtrate was evaporated to give 0.13 g of N1 -tert.butyl-4(R)-hydroxy-L-prolinamide which was used in the next step without further purification.
