実験手順

Trifluoroacetic acid (3 mL) was added to tert-butyl 4-(2-amino-1-(4-chlorophenyl)ethylcarbamoyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidin-4-ylcarbamate (Intermediate 6) (0.514 g) in DCM (100 mL) at 25° C. The resulting solution was stirred at 25° C. for 3 hours. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness. The crude product was purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5μ silica, 19 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness. This material was then further purified by flash silica chromatography, elution gradient 0 to 10% methanolic ammonia (7N) in DCM. Pure fractions were evaporated to dryness to afford 4-amino-N-(2-amino-1-(4-chlorophenyl)ethyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide as a colourless gum (0.047 g, 11.4%).
