Reaction Steps

To a solution of 8-cyclopentyl-4-methyl-2-(methylamino)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-ylboronic acid (30 mg, 0.099 mmol), 3-bromo-4-fluorobenzylamine hydrochloride (28.7 mg, 0.119 mmol), potassium carbonate (3 M, 0.10 mL) in DME (0.5 mL) and EtOH (0.5 mL) was added tetrakis(triphenylphosphine) palladium(0) (6 mg, 0.005 mmol). The mixture was degassed with N2, sealed and heated for 1 h at 100° C. in microwave. The mixture was removed under reduced pressure. The crude product was purified by chromatography to give the title compound (16.4 mg, 43.3%).
