Reaction Steps

To a solution of 4-((4-chloro-5-iodopyrimidin-2-yl)amino)benzonitrile (J12, 53 mg) and N-(4-pentynyl)phthalimide (47 mg) in N,N-dimethylformamide (1 mL), triethylamine (103 μL), copper(I) iodide (14 mg), and bis(triphenylphosphine)palladium(II) dichloride (10 mg) were added at room temperature, and the mixture was stirred overnight at the same temperature. To the reaction mixture, ethyl acetate and water were added. The organic layer was separated, washed successively with water and saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained solid matter was washed with chloroform, and then dried under reduced pressure to obtain 4-((4-chloro-5-(5-(1,3-dioxoisoindolin-2-yl)-1-pentyn-1-yl)pyrimidin-2-yl)amino)benzonitrile (J13, 44 mg) as white solid.
