実験手順: Borane-tetrahydrofuran complex (94.0 mL, 93.92 mmol) was added dropwise to a stirred suspension of 3-amino-3-(4-chlorophenyl)propionic acid (2.50 g, 12.52 mmol) in THF (75 mL) at 0° C. over a period of 20 minutes under nitrogen. The resulting suspension was stirred at 0° C. for 30 minutes then at 22° C. for 5 hours. The reaction mixture was added portionwise to methanol (500 mL). The mixture was concentrated, redissolved in methanol (250 mL) and reconcentrated (this process was repeated three times). The residue was dissolved in DCM (200 mL) and washed with 1N NaOH (150 mL). The aqueous layer was extracted with DCM (5×100 mL) and the extracts combined with the organic layer. The combined organics were washed with saturated brine (2×150 mL), dried over MgSO4 and concentrated to afford a white semi-solid. The crude product was purified by flash silica chromatography, elution gradient 5 to 7% (10:1 MeOH/conc. NH3 (aq)) in DCM. Pure fractions were evaporated to dryness to afford 3-amino-3-(4-chlorophenyl)propan-1-ol (1.320 g, 56.8%) as a white solid. at 22° C. for 5 hours The mixture was concentrated redissolved in methanol (250 mL) The residue was dissolved in DCM (200 mL) washed with 1N NaOH (150 mL) The aqueous layer was extracted with DCM (5×100 mL) The combined organics were washed with saturated brine (2×150 mL) dried over MgSO4 concentrated to afford a white semi-solid The crude product was purified by flash silica chromatography, elution gradient 5 to 7% (10:1 MeOH/conc.

The resulting solution was stirred at 50° C. for 10 minutes then cooled to ambient temperature. 3-Amino-3-(4-chlorophenyl)propan-1-ol (Intermediate 29) (49.5 mg, 0.27 mmol) was added as a solution in NMP (2 mL) and the mixture was stirred at 22° C. for 16 hours. 4M HCl in dioxane (1 mL) was added and the mixture was stirred at 22° C. for a further 24 hours. The mixture was concentrated and the residue was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 30% (2M NH3 in MeOH) in DCM and pure fractions were evaporated to dryness to afford crude product. 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 to afford 4-(aminomethyl)-N-(1-(4-chlorophenyl)-3-hydroxypropyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (0.095 g, 81%) as a white solid. then cooled to ambient temperature the mixture was stirred at 22° C. for 16 hours the mixture was stirred at 22° C. for a further 24 hours The mixture was concentrated the residue was purified by ion exchange chromatography The desired product was eluted from the column pure fractions were evaporated to dryness to afford crude product The crude product was purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5μ silica, 19 mm diameter, 100 mm length) Fractions containing the desired compound were evaporated to dryness
