実験手順

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.209 g) was added in one portion to 4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (Intermediate 1) (0.181 g), 1-(4-chlorophenyl)propan-1-amine (0.085 g) and DIPEA (0.262 mL) in DMA (10 mL) at 25° C. under nitrogen. The resulting solution was stirred at 60° C. for 4 hours. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7N ammonia/MeOH and pure fractions were evaporated to dryness. This crude material was then treated with a 20% solution of TFA in DCM (10 mL) and stirred at room temperature for 2 hours. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7N ammonia/MeOH and pure fractions were evaporated to dryness. This material was purified by preparative LCMS using decreasingly polar mixtures of water (containing 1% ammonia) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford 4-amino-N-(1-(4-chlorophenyl)propyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide as a white solid (0.138 g, 66.8
