Into a 100-mL round-bottom flask, was placed 3-[4-(3-fluorophenoxy)phenyl]-1-[(2R)-pyrrolidin-2-ylmethyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (216 mg, 0.53 mmol, 1.00 equiv), 2-cyanoacetic acid (36.8 mg, 0.43 mmol, 0.80 equiv), HATU (166 mg, 0.44 mmol, 0.80 equiv), triethylamine (109 mg, 1.08 mmol, 2.00 equiv), N,N-dimethylformamide (50 mL). The resulting solution was stirred for 3 h at 25° C. The resulting solution was extracted with ethyl acetate and the organic layers combined and concentrated under vacuum. The residue was loaded on a silica gel column and eluted with dichloromethane methanol (50 1) to give 150 mg (60%) of 3-[(2R)-2-([4-amino-3-[4-(3-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidin-1-yl]-3-oxopropanenitrile as a yellow solid.
