Procedure

To a stirred suspension of 3-((4-amino-3-(hydroxymethyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)-8-methyl-2-o-tolylisoquinolin-1(2H)-one (compound 4503) (50 mg, 0.12 mmol) in anhydrous DCM (2 mL) at 0° C. under an argon atmosphere, diethylaminosulfur trifluoride (DAST, 77 μL, 0.59 mmol) was slowly added and the resulting mixture was stirred from 0° C. to room temperature for 5 h. The reaction was quenched with water and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by prep-TLC plate (7% MeOH/DCM) to afford the desired product, 3-((4-amino-3-(fluoromethyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)-8-methyl-2-o-tolylisoquinolin-1(2H)-one (4504, compound 310 in Table 4) (10.3 mg, 20% yield) as a white solid.
