Trifluoroacetic acid → (S)-2-(4-chlorophenyl)-3-(isopropylamino)-1-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propan-1-one

Reaction Steps

(S)-tert-Butyl 2-(4-chlorophenyl)-3-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (0.041 g, 0.065 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 (S)-2-(4-chlorophenyl)-3-(isopropylamino)-1-(4-(5-(3-methoxyphenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)propan-1-one (0.028 g, 81% yield) as the dihydrochloride salt. MS ESI (+) m/z 533 detected.
