Procedure

A mixture of {1-piperidin-4-yl-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile trihydrochloride (1.22 g, 2.03 mmol), 3-fluoro-2-(trifluoromethyl)isonicotinic acid (460 mg, 2.2 mmol), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (1.07 g, 2.42 mmol), and triethylamine (2.0 mL, 14 mmol) in dimethylformamide (DMF) (20.0 mL) was stirred at room temperature overnight. LS-MS showed the reaction was complete. EtOAc (60 mL) and saturated NaHCO3 aqueous solution (60 mL) were added to the reaction mixture. After stirring at room temperature for 10 minutes, the organic phase was separated and the aqueous layer was extracted with EtOAc three times. The combined organic phase was washed with brine, dried over anhydrous Na2SO4, filtered and evaporated under reduced pressure. Purification by flash chromatography provided the desired product {1-{1-[3-fluoro-2-(trifluoromethyl)isonicotinoyl]piperidin-4-yl}-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile. LC-MS: 684.3 (M+H)+.
