실험 절차

Combine 2-[4-(2-Benzoylsulfanyl-3-phenyl-propionyl-amino)-3-oxo-1,3,4,5-tetrahydro-benzo[c]azepin-2-yl]-4-methyl-valeric acid, tert-butyl ester (0.229 mmol) in degassed methanol (3 mL) and cool in an ice bath. Treat with degassed 1N aqueous lithium hydroxide (1.0 mL) and stir, allowing the ice bath to warm gradually over 3 hours. With the reaction at 0° C., acidify with 5% hydrochloric acid. Partition between methylene chloride and water, dry (Na2SO4) and purify by silica gel chromatography to give the title compound.
