2-Cyclopropyl-8-methyl-3-((1S)-1-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-ylamino)ethyl)isoquinolin-1(2H)-one (compound 5004) (222 mg, 0.5 mmol) was dissolved in HCl/EtOH (3 M, 5 mL) and the resulting mixture was stirred at room temperature for 1 h. The reaction mixture was neutralized with saturated NaHCO3 solution to pH=7-8, and then 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 (1:1). The solid was collected by filtration and dried in vacuo to afford the desired product, (S)-3-(1-(9H-purin-6-ylamino)ethyl)-2-cyclopropyl-8-methylisoquinolin-1(2H)-one (5005, compound 200 in Table 4) (150 mg, 83% yield) as a white solid.
