Potassium Carbonate → 7-isobutyl-5-methyl-3-(phenylamino)-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)-2H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione

Participants

Reaction Steps

A mixture of 7-isobutyl-5-methyl-3-(phenylamino)-1H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione (12.0 mg, 0.0383 mmol), 2-(4-(bromomethyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.0383 mmol) and potassium carbonate (5.3 mg, 0.0383 mmol) in acetone (2.5 mL) is stirred at room temperature overnight. The solvent is evaporated under reduced pressure. The residue is directly purified by chromatography to give 7.0 mg product as white solids (Yield: 38.0%). MS (ESI) m/z 530.3 [M+H]+.
