Procedure
To a suspension of 4-amino-2-((S)-2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidine-1-carbonyl)-4-methylpent-2-enenitrile (210 mg, 0.39 mmol, 1.0 equiv), KI (130 mg, 0.78 mmol, 2.0 equiv) and potassium carbonate (166 mg, 1.17 mmol, 3.0 equiv) in CH3CN (15 mL) was added 1-bromo-2-methoxyethane (160 mg, 1.17 mmol, 3.0 equiv). The resulting suspension was stirred at 50° C. overnight. The solvent was removed under reduced pressure and then water (20 mL) was added to the residue. The resulting mixture was extracted with ethyl acetate (30 mL*3). The organic layers were combined, washed with brine, dried over sodium sulfate and concentrated. The residue was purified on Prep-HPLC. Conditions: (1#-Pre-HPLC-001(SHIMADZU)): Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, WATER WITH 0.5% NH4OH and CH3CN (40% CH3CN up to 100% in 20 min); Detector, 254 nm. This resulted in 8.7 mg (3.7%) of the title compound as an off-white solid. MS (ESI, pos. ion) m/z: 599 (M+1) H-NMR (400 MHz, CDCl3, ppm): 8.38 (s, 1H), 7.54 (t, J=8.4, 7.2 Hz, 1H), 7.45 (t, J=7.6, 8.0 Hz, 2H), 7.28-7.25 (m, 1H), 7.13 (d, J=8.0 Hz, 2H), 6.95 (dd, J=8.4, 2.0 Hz, 1H), 6.87 (dd, J=11.2, 2.4 Hz, 1H), 6.77 (s, 1H), 5.42 (brs, 2H), 4.93-4.90 (m, 1H), 4.83-4.82 (m, 1H), 4.70-4.65 (m, 1H), 3.67-3.65 (m, 5H), 3.36 (s, 3H), 3.36-3.31 (m, 1H), 2.20-2.89 (m, 3H), 1.88-1.71 (m, 1H), 1.61-1.51 (m, 4H), 1.35 (s, 3H), 1.33 (s, 3H).
