Procedure

To a mixture of N-{3-[(2-{[1-(1-methylpyrrolidin-3-yl)-1H-pyrazol-4-yl]amino}-9-{[2-(trimethylsilyl)ethoxy]methyl}-9H-purin-6-yl)oxy]phenyl}prop-2-enamide (271 mg, 0.471 mmol) in DCM (5.89 mL) was added TFA (1.81 mL, 23.6 mmol). The resulting solution was stirred at rt overnight, then concentrated and dried under vacuum. The resulting residue was taken up in water and neutralized with NaHCO3 to get a slightly sticky suspension. The solid was filtered off, washed with water, dried, and collected to give the crude product, which was purified by SFC to afford the title compound (21 mg, 10 yield) as a lyophilized solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 12.80 (br. s., 1H) 10.37 (br. s., 1H) 9.20 (br. s., 1H) 8.01-8.11 (m, 1H) 7.61-7.78 (m, 1H) 7.48 (br. s., 1H) 7.37 (d, J=6.32 Hz, 1H) 7.03 (d, J=7.33 Hz, 2H) 6.36-6.59 (m, 1H) 6.20-6.34 (m, 1H) 5.77 (dd, J=10.23, 1.89 Hz, 1H) 4.57 (br. s., 1H) 3.99-4.27 (m, 1H) 3.65-3.94 (m, 3H) 3.00 (br. s., 2H) 2.79 (m, J=15.66 Hz, 1H) 2.00 (br. s., 1H) 1.23 (s, 1H). m/z (APCI+) for C22H23N9O2 446.05 (M+H)+.
