Reaction Steps

To a solution of (S)-3-(1-((2-amino-5-iodopyrimidin-4-yl)amino)ethyl)-8-chloro-2-phenylisoquinolin-1(2H)-one 7 (700 mg, 1.35 mmol) in DMF (40 mL), cyanocopper (243 mg, 2.7 mmol), tetrakis(triphenylphosphine) palladium(0) (779 mg, 0.68 mmol), and copper iodide (180 mg, 0.95 mmol) were added and the resulting mixture was stirred at 80° C. for 16 h. The mixture was allowed to cool to RT, quenched with water and extracted with ethyl acetate (2×50 mL). The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel eluting with 0-10% MeOH-DCM to afford the product, (S)-2-amino-4-((1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carbonitrile 8.
