Reaction Steps

To a solution of cyclobutylmethanol (11 μL, 0.12 mmol) in methylene chloride (1 mL, 20 mmol) was added 2.02 M phosgene in toluene (0.045 mL, 0.091 mmol). After stirred for 2 hours, {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 (0.020 g, 0.040 mmol) and N,N-diisopropylethylamine (0.040 mL, 0.23 mmol) were added and was stirred overnight. The solvent was removed by rotary evaporation to give an oil. The oil was then dissolved in 1 mL methanol and 100 microL ethylenediamine was added. After 1 hour, the reaction was purified by prep-HPLC (pH10) using a Waters XBridge C18, 5 μm particle size, 19×100 mm; mobile phase system: aqueous (0.1% NH4OH)/acetonitrile; flow rate: 30 mL/min; separation gradient: 40-60% B in 5 min to give 15 mg white solid a (78%). 1H NMR (400 MHz, DMSO): δ 12.08 (1H, br); 8.75 (1H, s); 8.62 (1H, s); 8.35 (1H, s); 7.55 (1H, m); 7.0 (1H, m); 3.9 (2H, d); 3.65 (4H, m); 3.5 (4H, m); 2.9 (2H, br); 2.38 (1H, m); 1.91 (2H, m); 1.77 (2H, m); 1.61 (5H, m); 1.03 (2H, m). LCMS (M+1): 475.
