Participants

Reaction Steps

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 (0.010 g, 0.020 mmol) and propyl chloroformate (3.0 μL, 0.026 mmol) in methylene chloride (1 mL, 20 mmol) was stirred for 1.5 h. TFA, 1 mL, was added. After 1 hour, the solvent was removed by rotary evaporation to give an oil. The oil was dissolved in 1 mL MeOH and 50 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 5.3 mg white solid (58%). 1H NMR (400 MHz, DMSO): δ 12.13 (1H, br); 8.83 (1H, s); 8.7 (1H, s); 8.42 (1H, s); 7.61 (1H, m); 7.05 (1H, m); 3.95 (2H, t); 3.75 (4H, m); 3.55 (4H, m); 3.0 (2H, br); 2.43 (1H, m); 1.65 (2H, m); 1.58 (2H, m); 1.15 (2H, m); 0.95 (3H, t). LCMS (M+1): 449.
