(S)-tert-Butyl 3-(4-(5-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-2-(4-chlorophenyl)-3-oxopropyl(isopropyl)carbamate (0.040 g, 0.066 mmol) was placed in DCM (3 mL). TFA (0.3 mL) was then added. The reaction was stirred at room temperature for 1 hour. The reaction was then concentrated to dryness, dissolved in minimal DCM, and added dropwise to a stirring solution of 1M HCl in ether. The solid product was filtered, washed with ether, and dried to give (S)-1-(4-(5-bromo-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)-2-(4-chlorophenyl)-3-(isopropylamino)propan-1-one (0.03 g, 90% yield) as the dihydrochloride salt. MS ESI (+) m/z 505 detected.
