Reaction Steps

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 (1.0 g, 2.1 mmol), 4-chloro-N-[(1R)-1-cyclopropylethyl]-2,5-difluorobenzamide (0.54 g, 2.1 mmol), cesium carbonate (2.0 g, 6.2 mmol), (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (0.13 g, 0.21 mmol) and palladium acetate (0.046 g, 0.21 mmol) in toluene (20 mL, 200 mmol) was stirred at 105° C. overnight. After the reaction mixture was cooled to room temperature, the solid was filtered off by celite, washed with ethyl acetate. The filtrate was concentrated. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in dichloromethylene (0-60%) to afford the desired product (0.48 g, 36%). LCMS (M+H)+: m/z=633.3.
