(S)-tert-Butyl 2-(4-chlorophenyl)-3-(4-(5-(4-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (30 mg, 0.048 mmol) in TFA (3 mL) was stirred for 30 minutes and then concentrated to dryness. The resulting residue was dissolved in minimal DCM (0.2 mL) and added to 2N HCl in ether. The resulting solid was filtered and dried under nitrogen to yield (S)-2-(4-chlorophenyl)-1-(4-(5-(4-fluorophenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-(isopropylamino)propan-1-one (23 mg, 91% yield) dihydrochloride. MS ESI (+) m/z 520 detected.
