N,N-Diisopropylethylamine (0.71 mL, 4.1 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 (0.70 g, 1.4 mmol) and 5-chloro-N-[1-(trifluoromethyl)cyclopropyl]pyrazine-2-carboxamide (0.36 g, 1.4 mmol) in NMP (5.0 mL). The reaction mixture was stirred at 125° C. for 2 h. The reaction mixture was worked up with saturated aqueous NaHCO3, and extracted with dichloromethylene (3×20 mL). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in dichloromethylene (0-80%) to afford the desired product (0.90 g). LCMS (M+H)+: m/z=639.2.
