Procedure

To a solution of 2-amino-6-bromo-8-cyclopentyl-4-methylpyrido[2,3-d]pyrimidin-7(8H)-one (100 mg, 0.31 mmol), 3-hydroxyphenylboronic acid (50 mg, 1.2 equiv), dichlorobis(triphenylphosphine)palladium(II) (6.5 mg, 009 mmol), DMF (2 mL) in a 10 mL microwave vial was added potassium carbonate (3 M, 0.8 mL). The solution was degassed with N2 for 10 min before being capped and heated in the microwave reactor for 10 min at 120° C. Once complete, the reaction was diluted with 1 N NaOH (10 mL) and EtOAc (50 mL). The EtOAc layer was separated, dried over MgSO4, filtered, and concentrated under reduced pressure. The crude product was submitted for chromatography purification. The title compound was obtained in (82.1 mg, 79% yield).
