Reaction Steps
Following the general method of Example 3, a slurry of {s-(R*,R*)]-2-{-[2-(1-carboxy-3-methylbutylcarbamoyl)-4-fluorophenyldisulfanyl]-5-fluorobenzoylamino}-4-methyl-pentanoic acid (2.1 g, 3.6 mmol) (from Preparation 21) in 8 mL acetonitrile and 25 mL dichloromethane was treated with bromine (0.7 g, 4.4 mmol) in 15 mL dichloromethane. The crude compound was recrystallized from methanol/water to afford 1.4 g of the title compound, mp 161°-162° C.
