Procedure

A mixture of (S)-3-(1-((9H-purin-6-yl)amino)ethyl)-2-phenyl-8-vinylisoquinolin-1(2H)-one (8) (120 mg, 0.29 mmol) and palladium (10% weight on carbon, 24 mg) in anhydrous MeOH (25 mL) was degassed and flushed with hydrogen (three cycles). The reaction mixture was stirred under a hydrogen atmosphere (hydrogen balloon) at RT for 1 h. The mixture was filtered through Celite and rinsed with ethyl acetate. The filtrate was concentrated in vacuo and the residue was purified by ISCO (silica gel cartridge, 0-10% MeOH-DCM) to afford the product, (S)-3-(1-((9H-purin-6-yl)amino)ethyl)-8-ethyl-2-phenylisoquinolin-1(2H)-one (9). ESI-MS m/z: 411.2 [M+H]+.
