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 (1.0 g, 2.0 mmol) in methylene chloride (DCM) (10 mL) were added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (1.2 g, 2.6 mmol), N,N-diisopropylethylamine (1.1 mL, 6.1 mmol), and 4-(dihydroxyboryl)-3-fluorobenzoic acid (0.37 g, 2.0 mmol). The mixture was stirred at room temperature overnight. Solvents were removed under reduced pressure and the residue was purified using HPLC to give 0.54 g (41%) of the corresponding product {4-[(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)carbonyl]-2-fluorophenyl}boronic acid. LC-MS: 659.3 (M+H)+.
