Reaction Steps

(R)-tert-Butyl 3-(4-chlorophenyl)-1-(4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-1-oxopropan-2-ylcarbamate (0.029 g, 0.051 mmol) was placed in DCM (3 mL) at room temperature. TFA (0.5 mL) was then added, and the reaction was stirred at room temperature for 1 hour. The reaction was then concentrated to dryness, and the resulting residue was dissolved in minimal DCM. The solution was added dropwise to a stirring solution of 1M HCl in ether. The resulting solid was filtered, washed with ether, and dried to give (R)-2-amino-3-(4-chlorophenyl)-1-(4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)propan-1-one (0.020 g, 72% yield) as the dihydrochloride salt. MS APCI (+) m/z 475 detected.
