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 The crude product was purified by ion exchange chromatography The desired product was eluted from the column were evaporated to dryness This crude material was then treated with a 20% solution of TFA in DCM (10 mL) stirred at room temperature for 2 hours The crude product was purified by ion exchange chromatography The desired product was eluted from the column were evaporated to dryness This material was purified by preparative LCMS Fractions containing the desired compound were evaporated to dryness
