Procedure

To a solution 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 (200 mg, 0.4 mmol) in THF (10 mL) and triethylamine (0.1643 mL, 1.179 mmol) was added 6-(dimethylamino)-2-fluoro-3-formylbenzonitrile (75.52 mg, 0.3929 mmol). The solution was stirred at room temperature for 30 minutes before the addition of sodium triacetoxyborohydride (249.8 mg, 1.179 mmol). The mixture was stirred at room temperature overnight. After addition of aqueous NaHCO3, and EtOAc, the organic layer was separated, washed with brine, dried over anhydrous Na2SO4 and concentrated. Purification by HPLC afforded 150 mg of the product 3-[(4-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}piperidin-1-yl)methyl]-6-(dimethylamino)-2-fluorobenzonitrile as a white solid. LC/MS: 669.2 (M+H)+.
