実験手順

Dissolve 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 (141 mg, 0.229 mmol) in methylene chloride (5 mL) and treat with anisole (0.12 mL, 1.15 mmol) then with trifluoroacetic acid (1.5M). Stir at room temperature for 15 hours, partition between ethyl acetate (25 mL) and brine (15 mL). Wash the organic layer with brine (15 mL), dry (Na2SO4) and purify by silica gel chromatography (1:1 hexane/ethyl acetate followed by 1:1:0.01 hexane/ethyl acetate/acetic acid) to give the title compound as a white solid (157 mg).
