실험 절차

Mix N-t-butyloxycarbonyl-N5 -benzyloxycarbonyl-ornithine, t-butyl ester (2.0 g, 5.0 mmol) and 10% palladium/carbon (0.5 g) in 95% ethanol (40 mL). Hydrogenate at room temperature at atmospheric pressure. Filter and evaporate the filtrate in vacuo to give N-t-butyloxycarbonyl-ornithine, t-butyl ester.
