Reaction Conditions

Reaction Steps

A mixture of 2-butoxy-8-methoxy-9H-purin-6-amine trifluoroacetate salt (200 mg) and potassium carbonate (236 mg) in dry DMF (2 mL) was heated at 60° C. with stirring for 1 h. 3-(2-Bromoethyl)tetrahydrofuran (123 mg) was added and the reaction was continued for 2 h. The mixture was quenched with water and extracted with EtOAc (×3). The combined organics were washed with water and brine, dried using a hydrophobic frit and evaporated to give an oil (265 mg). The crude material was purified by normal phase chromatography (ISCO) using 0-15% MeOH/EtOAc as eluent to give the title compound (102 mg).
