Procedure

To a stirred mixture of N-(2-hydroxyethyl)acetamide (110 mg, 1.07 mmol, 2.43 eq) in THF (20 mL) at 0° C., NaH (60% in mineral oil, 110 mg, 2.75 mmol, 6.25 eq) was added and the resulting mixture was stirred for 15 min. To this mixture, (S)-tert-butyl 6-(1-(1,8-dichloroisoquinolin-3-yl)ethylamino)-9H-purine-9-carboxylate 39 (200 mg, 0.44 mmol, 1.0 eq) was added. The resulting mixture was stirred at reflux for 2 h, cooled to RT and then poured into water (30 mL). The mixture was extracted with DCM (3×30 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 (3% MeOH-DCM) to afford the product (S)—N-(2-(3-(1-(9H-purin-6-ylamino)ethyl)-8-chloroisoquinolin-1-yloxy)ethyl)acetamide 40. ESI-MS m/z: 426.0 [M+H]+.
