実験手順
N-Ethyldiisopropylamine (1.676 ml, 9.62 mmol) was added to (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)piperidine-4-carboxamide (Intermediate 49) (1 g, 3.21 mmol) and 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (0.493 g, 3.21 mmol) in butan-1-ol (15 ml). The resulting solution was stirred at 60° C. for 18 hours. The reaction mixture was diluted with EtOAc (50 mL), and washed sequentially with water (25 mL) and saturated brine (25 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 6% MeOH with ammonia in DCM. Pure fractions were evaporated to dryness to afford (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (842 mg) as a white foam. (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide was stirred in ethyl acetate (7 mL) for 18 hours. The solid was collected by filtration, washed with a small amount of ethyl acetate and vacuum oven dried at 55° C. for 18 hours to afford (S)-4-amino-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.585 g, 42.5%) as a white solid. m/z (ES+) (M+H)+=429; HPLC tR=1.60 min.
