Versuchsvorschrift

MeOSuc-Phe-Gly-Leu-OH was prepared from Z-Phe-Gly-Leu-OH, as described above in Procedure C. Z-Phe-Gly-Leu-OH (4.00 g, 8.52 mmol) was dissolved in 100 mL of methanol and hydrogenated in the presence of 1.0 eq of anhydrous HCl and 0.50 g of 10% Pd on carbon overnight in a Parr apparatus. The resulting reaction mixture was filtered and solvent was evaporated to yield 3.1 g of H-Phe-Gly-Leu-OH as a foam.
