Procedure

To a solution of (S)-2-amino-4-((1-(8-(2-methoxypyrimidin-5-yl)-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carbonitrile 5 (34 mg, 0.070 mmol) in anhydrous toluene (4 mL) under argon, acetaldoxime (13 μL, 0.21 mmol), palladium(II) acetate (5 mg, 0.01 mmol) and triphenyl phosphine (5 mg, 0.017 mmol) were added and the resulting mixture was stirred at 80° C. for 3 h. The mixture was allowed to cool to RT and partitioned between water and ethyl acetate. The organic layer was washed with brine, dried with Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by ISCO column chromatography (silica gel cartridge, 0-10% MeOH/DCM) to afford the product, (S)-2-amino-4-((1-(8-(2-methoxypyrimidin-5-yl)-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carboxamide 11. ESI-MS m/z: 509.2 [M+H]+.
