Trifluoroacetic acid → N-(4-(4-(2-amino acetyl)piperazin-1-yl)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide

Participants

Reaction Steps

tert-Butyl 2-(4-(3-(nicotinamido)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-2-oxoethylcarbamate (0.013 g, 0.023 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. The resulting residue was 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 N-(4-(4-(2-amino acetyl)piperazin-1-yl)-5-phenyl-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (0.004 g, 38% yield) as the trihydrochloride salt. MS APCI (+) m/z 456 detected.
