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.
