Vorschrift

A solution of LiOH (279 mg, 6.6 mmol) in water (6 mL) was added to a solution of (S)-benzyl 3-(3,4-bis(benzyloxy)phenyl)-2-((S)-2-(2-morpholinoacetamido) propanamido)propanoate (1.1 g, 1.66 mmol) in MeOH (30 mL) at 0° C. with stirring. The reaction mixture was stirred for 3 h and then acidified with 2 N aqueous HCl to pH=3. The resulting mixture was concentrated and the residue was carried forward without further purification.
