Versuchsvorschrift
In a separate flask, a suspension of 2-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (500 mg) and 2-pentanol (3.8 mL) was heated to 50° C. Sodium hydride (396 mg, 60% dispersion) was added in portions and the reaction was stirred at 50° C. for 72 h. The reaction was cooled and quenched with water (10 mL) and was extracted with EtOAc (3×25 mL). The combined organics were washed with brine (30 mL), dried over MgSO4, filtered and concentrated in vacuo to give crude title compound as a yellow oil.
