Reaction Steps

Hydrogen chloride (4M in 1,4-dioxane, 1.01 mL, 4.05 mmol) was added to tert-butyl 4-(1-(4-chlorophenyl)-3-(dimethylamino)propylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 34) (0.045 g, 0.08 mmol) in a mixture of DCM (5 mL) and methanol (2 mL) at 22° C. The resulting solution was stirred at 22° C. for 16 hours. 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 and pure fractions were evaporated to dryness to afford 4-amino-N-(1-(4-chlorophenyl)-3-(dimethylamino)propyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.034 g, 92%) as a colourless gum.
