実験手順: To a suspension of (R)-5-(2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation B, 200 mg, 0.56 mmol) and 3-chloro-N-methylpropan-1-amine hydrochloride (177 mg, 1.23 mmol) in DMF (4 mL) was added N-methylmorpholine (0.25 mL, 2.30 mmol), followed by HATU (234 mg, 0.616 mmol). The reaction was stirred at ambient temperature for 18 hours, then diluted with H2O (10 mL), and extracted EtOAc (2×20 mL). The combined organic extracts were washed with brine (20 mL), dried (MgSO4), filtered, and concentrated. The crude product was purified by reverse-phase column chromatography, eluting with 5 to 60% acetonitrile/water to yield the desired product as a white foamy solid (129 mg, 52% yield). MS (apci) m/z=447.0 (M+H). extracted EtOAc (2×20 mL) The combined organic extracts were washed with brine (20 mL) dried (MgSO4) filtered concentrated The crude product was purified by reverse-phase column chromatography eluting with 5 to 60% acetonitrile/water
