Reaction Steps
2-((4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)-5-methyl-3-o-tolylthieno[2,3-d]pyrimidin-4(3H)-one (2406) (50 mg, 0.092 mmol), PPh3 (14.5 mg, 0.056 mmol, 0.6 eq) and 3-fluoro-5-hydroxyphenylboronic acid (2207) (17.2 mg, 0.11 mmol, 1.2 eq) were dissolved in a solution of DMF, ethanol and water (5 mL/2 mL/2 mL). To this mixture Pd(OAc)2 (4.14 mg, 0.018 mmol, 0.2 eq) and sodium carbonate (48.7 mg, 0.46 mmol, 5 eq) were added sequentially. The resulting mixture was degassed and back-filled with argon three times and then heated to 80° C. for 0.5 h with stirring. The reaction mixture was concentrated in vacuo to remove the organic solvent. The resulting residue was purified by a silica gel column chromatography to afford the desired product 2-((4-amino-3-(3-fluoro-5-hydroxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)-5-methyl-3-o-tolylthieno[2,3-d]pyrimidin-4(3H)-one (2407) (22.8 mg, 48.2% yield) as a yellow solid.
