실험 절차
The general method of Preparation 20 was followed using [S-(R*,R*)]-2-[2-[[2-(1-tert-butoxycarbonyl-3-methyl-butylcarbamoyl)-4-fluorophenyldisulfanyl]-5-fluorobenzoylamino]-4-methyl pentanoic acid tert-butyl ester (1.8 g, 2.6 mmol) in 20 mL dichloromethane, anisole (2 mL), and 20 mL trifluoroacetic acid. The crude product was recrystallized from methanol/water to afford 0.9 g of the title compound.
