実験手順
tert-butyl 4-(4-(3-(1H-indol-5-yl)-1H-pyrrolo[2,3-b]pyridin-5-yl)benzyl)piperazine-1-carboxylate (63 mg) was suspended in dichloromethane (2 mL) and treated with TFA (2 mL). The resulting mixture was stirred for 90 minutes at room temperature, after which the solvent was removed in vacuo. The residue was dissolved in EtOAc and washed with 10% sodium hydroxide solution, water, and brine. The organic layer was dried over MgSO4, and the solvent was removed in vacuo. MPLC silica gel chromatography (0-20% MeOH in dichloromethane) provided an analytical sample (10 mg, 408 M+H) of the title compound.
