Procedure

(S)-3-(1-Aminoethyl)-2-cyclopropyl-8-methylisoquinolin-1(2H)-one (242 mg, 1 mmol) (compound 5003), 6-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (344 mg, 1.44 mmol) and DIPEA (279 mg, 2.16 mmol) were dissolved in n-BuOH (20 mL), and the resulting mixture was stirred at reflux for 16 h. The reaction mixture was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (eluting with 30% to 50% Hex/EA) to afford the desired product, 2-cyclopropyl-8-methyl-3-((1S)-1-(9-(tetrahydro-2H-Pyran-2-yl)-9H-purin-6-ylamino)ethyl)isoquinolin-1(2H)-one (compound 5004) (288 mg, 65% yield) as a white solid.
