Trifluoroacetic acid (2 mL, 25.96 mmol) was added to (S)-tert-butyl (4-(1-(4-chlorophenyl)ethylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-yl)methylcarbamate (Intermediate 13) (0.257 g, 0.5 mmol) in DCM (20 mL) at 25° C. The resulting solution was stirred at 25° C. for 1 hour. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness. The crude product was purified by flash silica chromatography, elution gradient 0 to 10% 7N ammonia/MeOH in DCM. Pure fractions were evaporated to dryness to afford (S)-4-(aminomethyl)-N-(1-(4-chlorophenyl)ethyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.095 g, 46.0%) as a white solid.
