Versuchsvorschrift

After 1.75 g (2.6 mmols) of Z-PyroGlu-Ala-Arg(NO2)-CHA was suspended in a solvent mixture of 112.5 ml of MeOH, 27.7 ml of H2O and 9.8 ml of 1N-HCl, 1 g of palladium black was added to the suspension followed by catalytic reduction at 30° C. for 6 hours. After the reaction, the catalyst was filtered off and the solvent was removed by distillation under reduced pressure. The residue was purified through TOYOPEARL HW40F column using MeOH as a developing solvent to give 0.471 g (34.4%) of H-PyroGlu-Ala-Arg-CHA.HCl.
