Procedure

To a solution of tert-butyl 4-{3-cyano-2-[(methylsulfonyl)oxy]propyl}-1,4-diazepane-1-carboxylate (4.00 g, 11.1 mmol) and 4-(1H-pyrazol-4-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine (3.50 g, 11.1 mmol) in DMF (30 mL) was added potassium carbonate (4.6 g, 33 mmol). The resulting mixture was stirred at room temperature for 66 hours. The reaction solution was diluted with ethyl acetate (˜300 mL) then washed with water twice and brine. The organic solutions were dried over MgSO4, filtered, and concentrated. The residue was purified by silica gel column (0% to 10% methanol/DCM) to give the desired product as clear oil (6.5 g, 100%). LCMS calculated for C29H45N8O3Si(M+H)+: m/z=581.3.
