Reaction Steps

To a solution N-{3-[(5-fluoro-2-[(1-methyl-1H-pyrazol-3-yl)amino]-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)oxy]phenyl}prop-2-enamide (120 mg, 0.23 mmol) in DCM (10 mL) was added TFA (0.7 mL, 6.7 mmol). The reaction solution was stirred at rt for 4 hrs. The reaction was evaporated to dryness and EtOH (5 mL), water (1 mL), and K2CO3 (158 mg, 1.1 mmol) were added. The reaction mixture was stirred at rt for 2 hrs and concentrated to dryness, suspended in EtOAc and filtered. The filtrate was concentrated to dryness and then suspended in EtOAc (20 mL) and heated to 70° C. with stirring for 30 min. The mixture was then cooled to rt with stirring overnight. A light yellow solid precipitated over this time and was collected by filtration, washed with EtOAc (5 mL) and dried to afford the title compound (50.2 mg, 56% yield) as a pale yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.25 (br. s., 1H) 10.27 (s, 1H) 9.25 (s, 1H) 7.64 (s, 1H) 7.53-7.60 (m, 1H) 7.41 (t, J=8.06 Hz, 1H) 7.28 (d, J=1.26 Hz, 1H) 7.02 (dd, J=7.93, 1.89 Hz, 1H) 6.99 (s, 1H) 6.38-6.48 (m, 1H) 6.05 (br. s., 1H) 5.77 (dd, J=10.07, 1.51 Hz, 1H) 3.65 (s, 4H). m/z (APCI+) for C19H16FN7O2 394.1 (M+H)+.
