Procedure

A solution of 3-((S)-2-((4-amino-3-(4-(2,3-difluorophenoxy)-2-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (304.2 mg, 0.60 mmol, 1.00 equiv), cyclopropanecarbaldehyde (210 mg, 3 mmol, 5 equiv), piperidine (102 mg, 1.20 mmol, 2 equiv) in EtOH (20 mL) was stirred overnight at rt. The resulting mixture was concentrated under vacuum. Then concentrated and 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 90 mg (22.3%) of the title compound as a white solid. MS (ESI, pos. ion) m/z: 560 (M-TFA+1)H-NMR (400 MHz, CDCl3, ppm): 11.94 (brs, 1H), 8.27 (s, 1H), 7.62-7.58 (m, 1H), 7.19-7.13 (m, 2H), 7.04-6.98 (m, 2H), 6.91 (d, J=11.2 Hz, 1H), 6.81 (d, J=11.2 Hz, 1H), 6.01 (brs, 1H), 4.96-4.86 (m, 1H), 4.76-4.62 (m, 2H), 3.71-3.62 (m, 1H), 3.61-3.45 (m, 1H), 2.12-1.82 (m, 5H), 1.30-1.28 (m, 2H), 0.94˜0.89 (m, 2H).
