実験手順

(R)-tert-Butyl 4-(4-chlorophenyl)-2-methyl-5-(4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyridin-4-yl)piperazin-1-yl)-5-oxopentan-2-ylcarbamate (0.040 g, 0.065 mmol) was placed in DCM (3 mL). TFA (0.3 mL) was then added. The reaction was stirred for 1 hour and then concentrated to dryness. The resulting oil was dissolved in minimal DCM, and added to a stirring solution of 1M HCl in ether. The resulting solid was collected by filtration, washed with ether, and dried to give (R)-4-amino-2-(4-chlorophenyl)-4-methyl-1-(4-(3-methyl-5-phenyl-1H-pyrrolo[2,3-b]pyri din-4-yl)piperazin-1-yl)pentan-1-one (0.034 g, 89% yield) as the dihydrochloride salt. MS ESI (+) m/z 517 detected.
