Procedure

(S)-3-amino-3-(4-chlorophenyl)propan-1-ol (173 mg, 0.93 mmol) was added in one portion to 4-(tert-butoxycarbonylamino)-1-(5-cyclopropyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 64) (375 mg, 0.93 mmol) and DIPEA (0.489 mL, 2.80 mmol) in DMA (5 mL). O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (391 mg, 1.03 mmol) was added and the resulting solution was stirred at 20° C. for 24 hours. The reaction mixture was evaporated to dryness then diluted with EtOAc (75 mL), and washed sequentially with water (50 mL) and saturated brine (50 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford crude product. The crude product was purified by flash silica chromatography, elution gradient 2 to 6% MeOH with ammonia in DCM. Fractions were evaporated to afford (S)-tert-butyl 4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)-1-(5-cyclopropyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (420 mg, 79%) as a yellow gum.
