To 1,1-dimethylethyl 4-(4-amino-5-{1-[(3-methylphenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-piperidinecarboxylate (230 mg, 0.406 mmol) were added 1,4-Dioxane and 4N HCl in dioxane (4 mL, 16.00 mmol). The mixture was allowed to stir overnight at 50° C. The reaction was concentrated. The solid was sonicated with 1:1 Hexane:DCM and the solid was isolated by filtration to isolate 5-{1-[(3-methylphenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-(4-piperidinyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (188 mg, 80% yield) as a white solid as the trihydrochloride salt.
