Procedure

DIEA (0.103 mL, 0.592 mmol) was added to 5-phenyl-4-(piperazin-1-yl)-1H-pyrrolo[2,3-b]pyridine dihydrochloride (0.052 g, 0.15 mmol, see Example 19), (S)-2-((S)-1-(tert-butoxycarbonyl)pyrrolidin-2-yl)-2-(4-chlorophenyl)acetic acid (0.0503 g, 0.148 mmol, see Example F) and TBTU (0.0570 g, 0.178 mmol) in DCM (1 mL) and stirred at room temperature for 1 hour. The mixture was directly loaded onto a column and purified by chromatography (1:1 hexane:ethyl acetate) to give (S)-tert-butyl 2-((S)-1-(4-chlorophenyl)-2-oxo-2-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)ethyl)pyrrolidine-1-carboxylate as a solid. The solid was then 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-chlorophenyl)-1-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)-2-((S)-pyrrolidin-2-yl)ethanone dihydrochloride (0.062 g, 63%). MS ESI (+) m/z 500 detected.
