Procedure

The Boc-Gly-Phe-Leu-OBzl (1.7 g) obtained in Example 19 was dissolved in a mixed solution of ethyl acetate (30 ml) and methanol (30 ml), and added with 5% Pd—C (1.5 g) to perform catalytic reduction. The reaction mixture was filtered and the filtrate was evaporated to dryness under reduced pressure to give the title compound (1.15 g).

Workup

  1. filtrationThe reaction mixture was filtered
  2. customthe filtrate was evaporated to dryness under reduced pressure
