실험 절차

5-Phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyri dine dihydrochloride (0.0159 g, 0.0454 mmol, see Example 19), (S)-2-(4-bromophenyl)-2-((S)-1-(tert-butoxycarbonyl)-5,5-dimethylpyrrolidin-2-yl)acetic acid (0.017 g, 0.0412 mmol, see Example C) and TBTU (0.0159 g, 0.0495 mmol) in DCM (1 mL) were added to DIEA (0.0287 mL, 0.165 mmol) and stirred at room temperature for 1 hour. The mixture was directly loaded to column and purified by chromatography (1:1 hexane:ethyl acetate) to give (S)-tert-butyl 5-((S)-1-(4-bromophenyl)-2-oxo-2-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)ethyl)-2,2-dimethylpyrrolidine-1-carboxylate as a solid. The solid was dissolved in DCM (1 mL), and TFA (0.2 mL) was added. The mixture was stirred at room temperature for 1 hour. The solvent was removed. The residue was dissolved in DCM (0.5 mL) and 2M HCl in ether (1 mL) was added. The resulting solid was collected by filtration to give (S)-2-(4-bromophenyl)-2-((S)-5,5-dimethylpyrrolidin-2-yl)-1-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)ethanone dihydrochloride (0.025 g, 95%). MS APCI (+) m/z 574 detected.
