Reaction Steps

To a solution of (S)-3-(1-((2-chloro-5-iodopyrimidin-4-yl)amino)ethyl)-8-(1-methyl-1H-pyrazol-4-yl)-2-phenylisoquinolin-1(2H)-one (64) (964 mg, 1.65 mmol) in anhydrous 1,4-dioxane (5 mL) in a sealed tube, ammonium hydroxide (6 mL) was added and the resulting mixture was stirred at 110° C. for 16 h. An additional amount of ammonium hydroxide (3 mL) was added to the reaction mixture and stirring was continued for 16 h. The mixture was allowed to cool to RT, quenched with water and extracted with ethyl acetate (100 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 (silica gel cartridge, 0-8% MeOH-DCM) to afford the product, (S)-3-(14(2-amino-5-iodopyrimidin-4-yl)amino)ethyl)-8-(1-methyl-1H-pyrazol-4-yl)-2-phenylisoquinolin-1(2H)-one (65) (532 mg, 57% yield) as a light tan solid. ESI-MS m/z: 564.0 [M+H]+.
