Komponenten

Versuchsvorschrift

This compound was prepared according to the procedure described in Example 50 using [S-(R*,R*)]-2-{2-[2-(1,4-bis-tert-butoxycarbonyl-butylcarbamoyl)phenyldisulfanyl]-benzoylamino}-hexanedioic acid di-tert-butyl ester (1.1 g, 1.4 mmol) from Example 10 mL dichloromethane, 10 mL trifluoroacetic acid, and 1 mL anisole. The crude product was recrystallized from methanol/dimethylformamide/water to afford 0.6 of the title compound, mp 259°-260° C.
