Reaction Conditions

Reaction Steps

To a suspension of 2-chloro-1H-purin-6-amine (1.57 g) and potassium carbonate (2.57 g) in DMF (55 mL) was added 4-(bromomethyl)tetrahydro-2H-pyran (2.0 g) in one portion. The mixture was stirred at 90° C. overnight. The reaction mixture was taken up in chloroform/isopropanol (3:1, 100 mL) and was extracted with water (100 mL). The organics were separated and the aqueous was extracted with chloroform/isopropanol (3:1, 2×50 mL). The organics were combined, dried by passing through a hydrophobic frit and concentrated in vacuo to give the title compound as an off-white solid (1.30 g, 52%).
