Procedure

Into a 10 mL round-bottom flask, was placed 3-[(2R)-2-[[4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-3-oxopropanenitrile (100 mg, 0.21 mmol, 1.00 equiv), piperidine (18 mg, 0.21 mmol, 1.00 equiv), cyclopropanecarbaldehyde (30 mg, 0.43 mmol, 2.00 equiv), and methanol (5 mL). The resulting solution was stirred for 12 h at 25° C. and then concentrated under vacuum. The residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (50/1) to give 38 mg (33%) of the title compound as a off-white solid.
