Participants

Reaction Steps

To a solution of 4-(3-aminophenoxy)-5-fluoro-N-(1-methyl-1H-pyrazol-3-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine (197 mg, 0.42 mmol) in DCM (20 mL) was added acryloyl chloride (34 μL, 0.42 mmol) and the reaction was stirred at rt for 45 min. Additional acryloyl chloride (34 μL, 0.42 mmol) was added and after another 2 hrs a final charge of acryloyl chloride (34 μL, 0.42 mmol) was added. After 30 min, the reaction was complete and was partitioned between DCM (30 mL) and saturated aqueous NaHCO3 (10 mL). The organic layer was separated, dried over Na2SO4 and evaporated to dryness. Purification via flash chromatography eluting with a gradient of 0%-80% EtOAc in heptane afforded the title compound (123 mg, 56 yield) as a solid. 1H NMR (400 MHz, methanol-d4) δ ppm 7.64 (s, 1H) 7.57 (d, J=8.81 Hz, 1H) 7.41 (t, J=8.18 Hz, 1H) 7.27 (d, J=1.76 Hz, 1H) 7.01 (dd, J=8.18, 2.14 Hz, 1H) 6.89 (d, J=2.27 Hz, 1H) 6.30-6.48 (m, 3H) 5.76 (dd, J=9.44, 2.14 Hz, 1H) 5.48 (s, 2H) 3.71 (s, 3H) 3.58 (t, J=8.06 Hz, 2H) 0.90 (t, J=8.06 Hz, 2H) −0.08 (s, 9H). m/z (APCI+) for C25H30FN7O3Si 524.2 (M+H)+.
