Potassium Carbonate → HCID 57699706、化合物

A mixture of 2-(butyloxy)-8-(methyloxy)-1H-purin-6-amine trifluoroacetate (0.2 g, 0.569 mmol) and anhydrous potassium carbonate (0.315 g, 2.277 mmol) in DMF was heated at 60° C. for 1 hour. The mixture was cooled to room temperature and 4-(2-bromoethyl)-2,2-dimethyltetrahydro-2H-pyran (0.151 g, 0.683 mmol) was added and the mixture heated at 50° C. for 18 hours. The mixture was quenched with water (2 ml) and extracted with DCM (2×5 ml). The DCM was separated through a hydrophobic frit and evaporated by blowing down under a stream of nitrogen. Addition of DMSO:MeOH (1:1) gave a precipitate which was collected by filtration, washed with methanol and dried in vacuo to give the title compound (29 mg).
