Procedure
O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (30.9 mg, 0.08 mmol) was added to 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (28 mg, 0.08 mmol) and N,N-diisopropylethylamine (0.016 mL, 0.09 mmol) in NMP (5 mL) at 22° C. The resulting suspension was stirred at 50° C. for 10 minutes. The mixture was cooled to ambient temperature and 3-amino-3-(4-chlorophenyl)propane-1-sulfonamide (Intermediate 104) (19.27 mg, 0.08 mmol) was added as a solution in NMP (2 mL). The mixture was stirred at 22° C. for 3 days. The mixture was diluted with methanol and loaded onto an SCX column. The crude product was purified by ion exchange chromatography; the desired product was eluted from the column using 2M NH3/MeOH and pure fractions were evaporated to dryness. The crude product was purified by flash silica chromatography, elution gradient 2 to 6% (10:1 MeOH/conc. NH3 (aq)) in DCM. Pure fractions were evaporated to dryness to afford tert-butyl 4-(1-(4-chlorophenyl)-3-sulfamoylpropylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (16.00 mg, 34.9%) as a white solid.
