Reaction Steps

Hydrogen chloride (4M in 1,4-dioxane, 1.151 mL, 4.60 mmol) was added to tert-butyl 4-(1-(4-chlorophenyl)-3-methoxypropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 101) (50 mg, 0.09 mmol) in a mixture of DCM (5 mL) and methanol (2 mL) at 22° C. The resulting solution was stirred at 22° C. for 2 days. The mixture was evaporated and the residue was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 2M NH3/MeOH; pure fractions were evaporated to dryness and the residue was triturated with diethyl ether to afford 4-amino-N-(1-(4-chlorophenyl)-3-methoxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (39.0 mg, 96%) as a white solid.
