Procedure

Boc-D-Tyr(Me)-L-Ile-D-Pro-OBzl (1.01 g, 1.70 mmol) was dissolved in methanol (20 ml) and subjected to catalytic hydrogenation in the presence of 5% Pd-C (150 mg). After 8 hours, the catalyst Pd-C was filtered and the reaction solution was evaporated to obtain Boc-D-Tyr(Me)-L-Ile-D-Pro-OH.

Workup

  1. filtrationthe catalyst Pd-C was filtered
  2. customthe reaction solution was evaporated
