Reaction Steps

HCl in 1,4-dioxane (4M) (0.228 mL, 0.91 mmol) was added to tert-butyl 4-(3-amino-1-(4-chlorophenyl)-3-oxopropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 108) (99 mg, 0.18 mmol) in DCM (4 mL) at 20° C. The resulting solution was stirred at 20° C. for 3 hours. The reaction mixture was filtered through a PTFE cup and the collected solid was purified by preparative HPLC (Waters XTerra C18 column, 5μ silica, 30 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford 4-amino-N-(3-amino-1-(4-chlorophenyl)-3-oxopropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (9.00 mg, 11.1%) as a cream solid.
