Procedure

To a solution of (S)-2-amino-4-((1-(8-(1-methyl-1H-pyrazol-4-yl)-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carbonitrile (69) (30.4 mg, 0.066 mmol) in anhydrous toluene (1 mL), acetaldoxime (10 μL, 0.13 mmol), palladium acetate (2 mg, 0.0066 mmol) and triphenyl phosphine (4 mg, 0.013 mmol) were added and the resulting mixture was stirred at 80° C. for 2 h. Additional amounts of acetaldoxime (10 μL, 0.13 mmol), palladium acetate (2 mg, 0.0066 mmol) and triphenyl phosphine (4 mg, 0.013 mmol) were added and stirring was continued at 80° C. for 2 h. The mixture was allowed to cool to RT, quenched with water (30 mL), and then extracted with ethyl acetate (30 mL×2). 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 ISCO column chromatography (silica gel cartridge, 0-8.5% MeOH-DCM) to afford the desired product, (S)-2-amino-4-((1-(8-(1-methyl-1H-pyrazol-4-yl)-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carboxamide (79) as a white solid. ESI-MS m/z: 481.2 [M+H]+.
