Procedure

O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate (98 mg, 0.26 mmol) was added in one portion to 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (62.2 mg, 0.17 mmol) and N,N-diisopropylethylamine (0.085 mL, 0.52 mmol) in NMP (2 mL) at 20° C. under nitrogen. The resulting solution was stirred at 20° C. for 5 minutes. N-(3-amino-3-(4-chlorophenyl)propyl)acetamide (Intermediate 27) (39 mg, 0.17 mmol) in NMP (2 mL) was then added to the reaction and stirred for 1 hour. The reaction mixture was concentrated and diluted with EtOAc (20 mL) and washed with water (20 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford tert-butyl 4-(3-acetamido-1-(4-chlorophenyl)propylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (1.04 g, 86%) as a white solid. m/z (ESI+) (M+H)+=570; HPLC tR=1.95 min.
