Procedure

3-(4-Amino-1-((8-methyl-1-oxo-2-o-tolyl-1,2-dihydroisoquinolin-3-yl)methyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-5-fluorophenyl diethyl phosphate 4302 (170 mg, 0.26 mmol) was dissolved in anhydrous CH3CN (5 mL) and cooled to 0° C. under an argon atmosphere. TMSBr (0.34 mL, 2.64 mmol) was slowly added via a syringe and the resulting mixture was stirred from 0° C. to RT for 16 h. LC-MS showed small amount of staRT ing material left, additional amount of TMSBr (0.1 mL) was added and stirred at RT for 5 h. LC-MS showed the complete conversion. The mixture was concentrated in vacuo, and the residue was dissolved in Et2O (10 mL) and H2O (0.5 mL) and stirred for 30 min. The mixture was concentrated in vacuo to affords the desired product, 3-(4-amino-1-((8-methyl-1-oxo-2-o-tolyl-1,2-dihydroisoquinolin-3-yl)methyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-5-fluorophenyl dihydrogen phosphate 4303 (140 mg, 91% yield).
