Reaction Steps

(S)-tert-Butyl 2-(4-chlorophenyl)-3-oxo-3-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)propyl(isopropyl)carbamate (0.003 g, 0.0050 mmol) was placed in DCM (2 mL) at room temperature. TFA (0.4 mL) was then added, and the reaction was stirred for 1 hour. The reaction was concentrated to dryness. The crude residue was dissolved in minimal DCM and added dropwise to a stirring solution of 1M HCl in ether (10 mL). The solid product was then filtered, washed with ether, and dried to give (S)-2-(4-chlorophenyl)-3-(isopropylamino)-1-(4-(5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propan-1-one (0.001 g, 40% yield) as the dihydrochloride salt. MS ESI (+) m/z 503 detected.
