実験手順

O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate (0.579 g, 1.52 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) (0.5 g, 1.38 mmol) and DIPEA (0.503 mL, 3.04 mmol) in NMP (5 mL) at 20° C. The resulting solution was stirred at 20° C. for 5 minutes. (R)-methyl 3-amino-3-(4-chlorophenyl)propanoate (hydrochloride) (Intermediate 40) (0.346 g, 1.38 mmol) was then added to the solution and stirred at room temperature for 3 hours. The reaction mixture was diluted with EtOAc (100 mL), and washed sequentially with water (50 mL), water (50 mL), and water (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 0 to 5% MeOH in DCM. Pure fractions were evaporated to dryness to afford (R)-methyl 3-(4-(tert-butoxycarbonylamino)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamido)-3-(4-chlorophenyl)propanoate (0.800 g, 100%) as a white solid.
