Reaction Steps

6.27 g of methyl 4-azido-1-[3-(4-tert-butyloxycarbonylaminomethylphenyl)propionyl]prolinate (starting material A5) are dissolved in 200 ml of methanol and, after addition of 0.6 g of Pd/C (10%), hydrogenated. After the reaction has ended, the catalyst is filtered off with suction and the filtrate is concentrated under reduced pressure. Drying under high vacuum gives 5.47 g of the title compound as a colorless solidified foam. The mass spectrum shows the molecular peak MH+ at 406 Da.
