Procedure

A solution of 3-(4-(2,3-difluorophenoxy)-2-fluorophenyl)-1-((R)-pyrrolidin-2-ylmethyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (50 mg, 0.12 mmol, 1.00 equiv), 2-cyanoacetic acid (14 mg, 0.18 mmol, 1.50 equiv), HATU (52 mg, 0.18 mmol, 1.5 equiv) and TEA (42 mg, 0.40 mmol, 5.00 equiv) in N,N-dimethylformamide (10 mL) was stirred overnight at 25° C. It was quenched with water (50 mL), which was extracted with EA. The organic layers were combined, washed with brine, dried over sodium sulfate, filtrated and concentrated. The residue was submitted to flash chromatography (SiO2, PE:EtOAc=2:1 to 1:1) to give 48 mg (83%) of 3-((R)-2-((4-amino-3-(4-(2,3-difluorophenoxy)-2-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile as a yellow solid.
