Versuchsvorschrift

This compound was prepared according to the procedure described in Example 50 using 4,4'-[dithiobis(2,1-phenylenecarbonylimino)]bis butanoic acid bis (1,1-dimethylethyl) ester (0.5 g, 0.9 mmol) from Example 43, 10 mL dichloromethane, 10 mL trifluoroacetic acid, and 1 mL anisole. The crude product was recrystallized from methanol/dimethylformamide/water to afford 0.6 g of the title compound, mp 165-166° C.
