Reaction Steps

3-(1-(2-Fluoro-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-ylamino)ethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (compound 5203) (160 mg, 0.32 mmol) was dissolved in HCl/EtOH (3 M, 5 mL) and the resulting mixture was stirred at room temperature for 1 h. The mixture was neutralized with saturated NaHCO3 aqueous solution to pH=7-8, and extracted with CH2Cl2 (50 mL×3). The combined organic layer was washed with brine, dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was recrystallized from ethyl acetate and hexanes. The solid was collected by filtration and dried in vacuo to afford the desired product, 3-(1-(2-fluoro-9H-purin-6-ylamino)ethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (5204, compound 245 in Table 4) (125 mg, 94% yield) as a white solid.
