Procedure

5-Phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine dihydrochloride (0.0200 g, 0.0570 mmol, see Example 19), (S)-2-((S)-1-(tert-butoxycarbonyl)-5,5-dimethylpyrrolidin-2-yl)-2-(4-chloro-3-fluorophenyl)acetic acid (0.020 g, 0.0518 mmol, see Example D) and TBTU (0.0200 g, 0.0622 mmol) in DCM (1 mL) were added to DIEA (0.0361 mL, 0.207 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-chloro-3-fluorophenyl)-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 resulting 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-chloro-3-fluorophenyl)-2-((S)-5,5-dimethylpyrrolidin-2-yl)-1-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)ethanone dihydrochloride (0.009 g, 28%). MS APCI (+) m/z 546 detected.
