실험 절차

2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl (0.11 g, 0.18 mmol) was added to a mixture of {3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile dihydrochloride (0.86 g, 1.8 mmol), methyl 4-bromo-3-fluorobenzoate (0.50 g, 2.1 mmol, Combi-Blocks: Cat. #CA-4107), and cesium carbonate (1.7 g, 5.4 mmol) in toluene (25.0 mL) under N2, followed by palladium acetate (0.040 g, 0.18 mmol). The reaction mixture was stirred at 120° C. for 5 hours. The reaction mixture was diluted with ethyl acetate, filtered, and concentrated under reduced pressure to afford the desired crude product (1.06 g) which was directly used in next step reaction without further purification. LCMS (M+H)+: m/z=562.3.
