الإجراء التجريبي

This compound was prepared according to the procedure described in Example 50 using [R-(R*,R*)] (2-{2-[(tert-butoxycarbonyl-phenyl-methyl)-carbamoyl]-phenyldisulfanyl}-benzoylamino)-phenyl-acetic acid tert-butyl ester (0.2 g, 0.3 mmol) from Example 38, 10 mL dichloromethane, and 10 mL trifluoroacetic acid. The crude product was stirred with ether/hexane and filtered to afford 73.0 mg of the title compound, mp 231°-232° C.
