Reaction Steps

To a stirred mixture of 1-isopropylpiperidin-4-ol (120 mg, 0.83 mmol, 1.2 eq) in THF (10 mL) at 0° C., NaH (60% in mineral oil, 33.2 mg, 0.83 mmol, 1.2 eq) was added and the resulting mixture was stirred for 10 min. To this mixture, (S)—N-(1-(1,8-dichloroisoquinolin-3-yl)ethyl)-9H-purin-6-amine 38 (250 mg, 0.70 mmol, 1.0 eq) was added. The resulting mixture was stirred at reflux overnight, cooled to RT and then poured into water (20 mL). The mixture was extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine, dried over Na2SO4, and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (5% MeOH-DCM) to afford the product, (S)—N-(1-(8-chloro-1-(1-isopropylpiperidin-4-yloxy)isoquinolin-3-yl)ethyl)-9H-purin-6-amine 47. ESI-MS m/z: 466.2 [M+H]+.
