実験手順
To a solution of (S)—S-3-(2-(tert-butoxycarbonylamino)-3-((4-methoxyphenyl)(methyl)amino)-3-oxopropyl)phenethyl ethanethioate (2.8 g, 5.74 mmol) in ethanol (20 ml) was added potassium hydroxide (0.64 g, 11.4 mmol). After 10 minutes, ethyl 2-(1-acetyl-2-(bromomethyl)-1H-indol-3-yl)acetate (2.2 g, 6.47 mmol) was added to the solution. The reaction was stirred for 2 hours at room temperature. The reaction was neutralized with 1N (aq) HCl and then extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and concentrated. The crude product was introduced to a silica gel loading column and purified by column chromatography (3-6% MeOH/DCM) to provide the desired product (2.0 g, 3.0 mmol), 52.3%. MS (m/z) 660 [M+H]+.
