Reaction Steps

A solution of 3-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl]-4,4-difluoropyrrolidin-1-yl]-3-oxopropanenitrile (120 mg, 0.24 mmol, 1.00 equiv), cyclopropanecarbaldehyde (80 mg, 1.14 mmol, 5.00 equiv), piperidine (41 mg, 0.48 mmol, 2.00 equiv) in ethanol (10 mL) was stirred at 70° C. for 2 h. The resulting mixture was concentrated under vacuum. 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, to give 24 mg (18%) of the title compound as a white solid. LC-MS m/z: 560 (M+1). H-NMR (400 MHz, CDCl3, ppm): 11.94 (brs, 1H) 8.29 (s, 1H), 7.55-7.45 (m, 3H), 7.31-7.24 (m, 1H), 7.14 (d, J=7.6 Hz, 2H), 7.00 (dd, J=8.8, 2.4 Hz, 1H), 6.90-6.87 (m, 1H), 6.07 (brs, 1H), 4.97-5.05 (m, 1H), 4.70-4.67 (m, 1H), 3.94-3.77 (m, 2H), 2.10 (s, 1H), 1.45-1.36 (m, 2H), 1.27-1.14 (m, 2H).
