Procedure

A solution of 3-((S)-2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (118 mg, 0.25 mmol, 1.0 equiv), 2-(cyclopropylamino)-2-methylpropanal (0.16 g, 1.25 mmol, 5.0 equiv) and one drop of piperidine in MeCN (10 mL) was stirred overnight at 40° C. The solvent was removed and 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 0.05% TFA and CH3CN (40% CH3CN up to 100% in 20 min); Detector, 254 nm. This resulted in 40 mg (27%) of the title compound as a white solid and bis TFA salt. LC-MS: m/z 581 (M+H+). H1-NMR (400 MHz, CDCl3+D2O, ppm): 8.33 (s, 1H), 7.54-7.43 (m, 3H), 7.33 (s, 1H), 7.28-7.25 (m, 1H), 7.07 (d, J=8.0 Hz, 2H), 6.94 (dd, J=8.4, 2.0 Hz, 1H), 6.85 (dd, J=11.6, 2.0 Hz, 1H), 4.89-4.64 (m, 3H), 3.65-3.52 (m, 2H), 2.78 (m, 1H), 2.14-1.79 (m, 4H), 1.57-1.55 (d, 6H), 1.20 (m, 2H), 0.98 (m, 2H).
