Procedure
O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 0.456 g) was added to 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (0.361 g), 2-amino-2-(4-chlorophenyl)acetonitrile (Intermediate 4) (0.167 g) and N-ethyldiisopropylamine (0.523 mL, 3.00 mmol) in DMA (5 mL) at 25° C. The resulting solution was stirred at 50° 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 to afford tert-butyl 4-((4-chlorophenyl)(cyano)methylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate as a white solid (0.343 g, 67.3%).
