Procedure

(R)-tert-Butyl 3-(4-chlorophenyl)-1-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-1-oxopropan-2-ylcarbamate (0.021 g, 0.036 mmol) was placed in DCM (3 mL) at room temperature. TFA (0.3 mL) was then added, and 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 (R)-2-amino-3-(4-chlorophenyl)-1-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propan-1-one (0.015 g, 86% yield) as the dihydrochloride salt. MS ESI (+) m/z 491 detected.
