Reaction Steps
(R)-tert-Butyl 2-(4-(5-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-1-cyclohexyl-2-oxoethylcarbamate (0.010 g, 0.019 mmol) was placed in DCM (3 mL) at room temperature. TFA (0.3 mL) was then added. 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-1-(4-(5-bromo-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)-2-cyclohexylethanone (0.005 g, 62% yield) as the dihydrochloride salt. MS ESI (+) m/z 421 detected.
