실험 절차

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (89 mg, 0.23 mmol) was added in one portion to a stirred solution of 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (80 mg, 0.22 mmol) and N-ethyldiisopropylamine (0.046 mL, 0.27 mmol) in NMP (3 mL). The mixture was treated with N-(2-amino-2-(4-chlorophenyl)ethyl)acetamide (Intermediate 83) (52 mg, 0.24 mmol). The solution was stirred for 65 hours at room temperature. The mixture was partitioned between ethyl acetate and water. The organic layer was washed twice with water. The organic solution was concentrated under reduced pressure. The residue was purified by flash column chromatography on silica using gradient elution (1% methanol/DCM to 15% methanol/DCM). Product containing fractions were combined to give tert-butyl 4-(2-acetamido-1-(4-chlorophenyl)ethylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (100 mg, 81%) as colourless solid.
