Potassium Carbonate → HCID 57699705, compound

Participants

Reaction Steps

2-[(Cyclohexylmethyl)oxy]-8-(methoxy)-9H-purin-6-amine trifluoroacetate salt (0.28 g) was heated with anhydrous potassium carbonate (0.3957 g) in anhydrous DMF (5 mL) under nitrogen for 1 hour at 60° C. (external). The reaction mixture was cooled to room temperature before adding 4-(bromomethyl) tetrahydro-2H-pyran (0.14 g) in anhydrous DMF (1 mL). The reaction mixture was heated to 50° C., overnight. The reaction mixture was quenched into water (20 mL) and extracted into ethyl acetate (20 mL, 3 times). The organic layers was separated, combined and then washed with brine (20 mL). The organic layer was separated and then dried by passing through a hydrophobic frit. Evaporation under reduced pressure gave pale yellow oil that solidified on standing. This was purified by C18 reverse phase chromatography using water (containing 0.1% formic acid)-acetonitrile (containing 0.05% formic acid) as eluent (30-80%) to give the title compound as a white solid (0.1677 g).
