Reaction Steps

tert-Butyl 3-(4-(3-(nicotinamido)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-oxopropylcarbamate (0.020 g, 0.035 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, dissolved in minimal DCM, and added to a stirring solution of 1M HCl in ether. The resulting solid product was filtered, washed with ether and dried to give the product N-(4-(4-(3-aminopropanoyl)piperazin-1-yl)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (0.008 g, 39% yield) as the trihydrochloride salt. MS APCI (+) m/z 470 detected.
