Reaction Steps

(S)-3-(1-Aminoethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (compound 4704) (100 mg, 0.36 mmol), 2-Amino-6-chloropurine (compound 5401) (60.9 mg, 0.36 mmol) and N,N-diisopropylethyl amine (69 μL, 0.40 mmol) were suspended in n-BuOH (4 mL) in a sealed tube, and the resulting mixture was stirred at 100° C. for 48 h and then at 120° C. for 24 h. The mixture was allowed to cool to room temperature and concentrate in vacuo to remove n-BuOH. The residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo. The residue was triturated with anhydrous ethyl ether and further purified by flash column chromatography on silica gel (eluting with 0-8% MeOH/DCM) to afford the desired product, (S)-3-(1-(2-amino-9H-purin-6-ylamino)ethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one as a off white/yellow solid (compound 5402), (28 mg, 20%).
